"Is Part Of?" keeps resetting

In my app the “Is Part Of” option keeps resetting to unchecked everytime reopen app editor. The feature will stay checked and stay functional in the app until I go back into the editor. Once I open the editor it automatically resets to unchecked. Does anybody has insight as to why this is happening?

It’s a Virtual Column. I do not think a Virtual Column can have the “Is part of” setting turned on. I think its a bug that it even shows in a VC.

You have the column [Calendar Reference]. If that is a “normal” column, then it is in that column that you would set the “Is part of” property to on.

If you do not have a “normal” column that is a Ref to your Calendar, then add one and set “Is part of”.
