--Module script Database

local UGC_ItemsDatabase = {
    ["8594752710"] = "accessory"; -- accessory
    ["6116917211"] = "pants"; -- pants
    ["7049798435"] = "shirt"; -- shirt
}

return UGC_ItemsDatabase

-- Server Script
print(UGC_ItemsDatabase["8594752710"]) -- prints "accessory"
print(UGC_ItemsDatabase["6116917211"]) -- prints nil
print(UGC_ItemsDatabase["7049798435"]) -- prints nil

When I run server the ID’s of pants and shirt change into their Template (Texture) ID instead of catalog https://www.roblox.com/asset-thumbnail/image?assetId=7049798435&width=420&height=420&format=png (thumbnail, what I want to achieve) https://www.roblox.com/asset-thumbnail/image?assetId=7049798428&width=420&height=420&format=png (what ID changes to)

Any help is appreciated, thank you!
