Hey!
Something similar happened to me too. Double-check whether your green bubbles correctly point to thisRow or CurrentValue. In my case, items that didn’t have the thisRow or CurrentValue prefix explicitly, they resolved to a wrong context and stopped working as expected.
Oh, and your formula generally looks wrong. You have your table mentioned twice before .AddOrModifyRows() and as a first parameter too — you do either but not both. Also, CurrentValue within AddOrModifyRows() is overwritten with currently edited row — I suggest rewrite the formula so that you only use AddRows(), and if you need nested CurrentValue, then a different approach would be required
