This is something I've done a few times before but now something seems weird.
I added a person field to my list. (No fancy settings just a new field where the type is person). When adding this field to my PowerApp (Not a people picker, just adding that column as a datacard), it displays with item 1 to 8 as options to select from. This is only true for name fields I've added since Sunday (Sunday and today to be exact).
The other name fields that I added to my form last month - works fine.
Any ideas?
