i was troubleshooting my data store script and realized that every time the player leaves instead of the data store updating the saved data it adds to it instead 
in this picture you can only see a small part of the output, it goes on for ever, each part is one save, if you know why its doing so please tell me, i’m sorry for the bad explanation
local DataStore = game:GetService("DataStoreService"):GetDataStore("PlayerOutfits1")
