Datastore2 Combining Issue

Hello,

I have currently got a TON of data saved using Datastore2 without combining, so I am individually requesting data for “Coins”, “Gems”, etc.
This is obviously causing my queue to fill and giving warnings.

I want to switch to combining my keys, but when I tried it in a demo place I lost all my data upon using Combine on my keys.

I still have my data in my original place so if anyone knows how I can move these to Combine, that would be much appreciated.
