Okay, first, here is my formula:
=IF([Release Name]@row = "", "", IF(COUNT(ANCESTORS()) = 0, 1))
It is in the far right (second image) in the column named Is Parent, which is a checkbox. I only noticed this issue as a result of checking on these release numbers that are a variation of the same number with letters as a "suffix". What concerns me is there can easily be more. This is set as a Column Formula in the Is Parent column. This sheet has over 2400 records, and will soon have a lot more, so I need to be confident that this is correct.
New: Release Update Sheet
on the same sheet, to the far RIGHT, the same rows show...
