Im using carbon on my test server and Im using dynamic settings.

I was troubleshooting why player reguardless of permission would only get 48 slots (even when they have the permission for 96) so I thought that maybe there was an issue with the order of the config (sort of like kits where it reads from top to bottom for auto spawn kits) so I reversed my config so that 96 slots showed before 48. I have 5 dynamic groups (48, 96, 144, 192 and 240) and now players have 240 slots instead of the one they are supposed to have.... even after setting the config back the way it origionally was players still have 240 even tho they dont have permission for 240. I even unloaded the addon and deleted all the data files and reloaded the addon and players still have 240 even tho no group currently has permissions for 240 slots... Im at a loss

Can you share your config?

From your description, it sounds like you are using the dynamic capacity feature (which designates a min/max capaity range and requires integration with other plugins to increase capacity through various events). When using that mode, capacity data is stored in the data/BackpacksCapacity.json file. I know you said you deleted "all" data files, but I just wanted to call out that file specifically in case you missed it.

Yes I deleted the folder that stores the items in the backpack and both the capacity and the other backpack file as well... 

I was able to reproduce one issue, where if you grant none of the size profile permissions, the first one applies. This is consistent with your account, which means the order does matter in that case. Otherwise, order is not applicable. It wasn't intended that the first profile apply if you don't have the permission for it, so I will make an update to determine size differently in that case.

I pushed a fix to the plugin's GitHub repo for testing, which fixes the issue where the first dynamic size profile applies even when you have no size profile permissions granted.

Thanks for providing both the config and permissions. I see you have granted two size-related permissions:

• backpacks.size.profile.48-480
• backpacks.size.profile.96-480

I'm assuming that you expect to have 96 capacity in that case (until you increase the capacity through other events). The reason that you are seeing 240 capacity is that the permission you titled "48-480" is actually configured with "Initial size" 240. It looks like this was a consequence of your attempt to reverse the order of the entries. It seems you reversed the names but not the actually capacity amounts. Or perhaps you had initially set the "Initial size" values in the reverse order before reversing the entries.

To resolve all inconsistencies, make the following changes:

• Update "240-480" to have "Initial size" 240 (currently 48)
• Update "192-480" to have "Initial size" 192 (currently 96)
• Update "96-480" to have "Initial size" 96 (currently 192)
• Update "48-480" to have "Initial size" 48 (currenlty 240)

For your convenience, here is that section of the config modified. Note that the order does not matter.

"Size profiles": [
  {
    "Permission suffix": "240-480",
    "Initial size": 240,
    "Max size": 480
  },
  {
    "Permission suffix": "192-480",
    "Initial size": 192,
    "Max size": 480
  },
  {
    "Permission suffix": "144-480",
    "Initial size": 144,
    "Max size": 480
  },
  {
    "Permission suffix": "96-480",
    "Initial size": 96,
    "Max size": 480
  },
  {
    "Permission suffix": "48-480",
    "Initial size": 48,
    "Max size": 480
  }
]

If you want to avoid the possible issue where the permission names do not match the actual capacity, simply rename the permissions to something that doesn't indicate the exact size (e.g., vip1, vip2, vip3, or big, bigger, biggest).
