If i name my store "Food Market" It will say item wasnt found when buying

If i rename it to "FoodMarket" It works perfectly fine lol
On occasions you need the same category name as the display name or it will break the NPC

Not sure why this happens its not 100% of the time

    "Food Market": {
      "DisplayName": "Food Market",
      "Description": "You currently have {0}$ To spend",
      "EnabledCategory": true,
      "EnableNPC": true,
      "NPCId": "7084851200",
      "Items": [
        "Pickles",
        "Small Water Bottle (Empty)",
        "Water Jug (Empty)"
      ]
    },

Update 1.9.1 appears to have broken several items/names from working in the shop. Recommend going back to 1.9.0 until I can work this name replace issue out with special characters better. 

Merged post

Update 2.0.0 should resolve this issue now with your shop names. I Will post it shortly
