I have set a variable OnStart Set(loggedinUser,User().Email)
When I go to use this variable in a Gallery Filer as show below, as you can see i receive the Incompatibility warning. I have tried in, Exactin, and =, but the person field named Owners throws a warning.

What I really want to know is why "Assigned To', 'Created By', 'Modified By' works yet a person field called Owners does not.
Thank you for your time
