An easy way is to rewrite your datastore using ProfileStore By loleris I have used this module and it is perfect for all your data store needs. Many other people use it as well. There is many tutorials out there on youtube and it can only take 20 minutes max to fully setup your game and make handling data easier.
Although if you wish to keep using Roblox’s Data Store Service and the limitations of it, let me know and we can figure out a solution.
