I have a new screen based on a “Project” table. I have a grid component on this screen to display related child records. The relation and dependent roll ups are all working as expected and the child table fields display correctly in my grid component, APART from a math column that is converting a date in the child table to YYMM number format.

Any ideas?

Can’t say for sure, but I wouldn’t mind betting that those Row Owners in your child table have something to do with it. Easy way to test that theory is to remove the row owners and see if anything changes.

Thanks for the response @Darren_Murphy  
I thought about row owners being responsible but would that not then preclude all the other fields from the child table being visible as well?

Very strange - I made a copy of the app (with copied sheet) to test removing row owners. Before I could even remove the row owners, the column was now visible in the copy and in the original app!  
At least working as expected now. 😕
