"Phantom" Errors vanish when I check them

[JohnMFranzen]

I have an app that I built in PowerApps, which contains a form linking to a SharePoint list. This form contains three drop-down fields. For some reason, whenever I open up this form to edit it, those three drop-downs all throw the same error in the Items property, "The data source supplied to the function is invalid." However, when I go to check the formula, PowerApps figures out that the formula is actually correct, and the problem goes away.

This has been happening every time I open up the app. The form still works, but I don't know why I keep on getting these phantom errors. Has anyone else had this happen to them, and what do you do to get around it?
