i posted here a while back talking about the issues with groups, ive gotten to a point where Owner and Admin appear just fine, however groups such as AdvancedVIP despite being fully setup exactly the same [except priority] does not appear ingame despite the player being in that specific group, instead all they get is "player" tag. 

does anyone at all know what ive done wrong, if anyone can help?

just to further onto my issue in HOPES for some help, my friend who is a donor has the respectible group assigned [AdvancedVIP] and when attempting to add him manually to said group, it already displays he is in. HOWEVER.

Despite him being within the group, the only tag that appears is "[Player]", do keep in mind the default 3 tags is still there, so the fact its not coming up what so ever is confusing. 

ive removed him from the group, added him back to it, ive remade the whole groups in the data file, ive even done a fresh updated install of BetterChat. and through it all, the only thing that works, is player, admin and owner. nothing else. 

does anyone have any tips or configs i could take a look at or something?

There's a video on youtube, discussing the trouble people face setting up the groups. 

I believe it's the following video.

Try this config. I've been using it for years. It's not actually my entire config (there are other ranks too) as I snipped the parts that I think are most relevant to you to paste here. It contains default, admin, moderator, helper, and 4 different vip ranks all with different tags and colours. Just edit it to your personal liking. I validated the JSON but if I've messed up the snipping let me know.

update: 

thank you for the help
however i finally figured it out after so long
turns out the issue was the permissions group was "BasicVIP" instead of "basicvip" turns out caps does matter
