Taking several examples from the community, I made a form in which I had a repeat section with several related lookup fields inside.
If on line 1 of the repeat section you selected one value in the lookup A, the lookup B was reloaded with the filtered values.
Line 2 of the repetition section was independent. You could select something in the lookup A that did not interfere with the line 1( Nothing changes on line 1)
This was working and in production.
Now, without modifying the form, line 1 works fine, but as soon as I add a line, I lose the values (already selected) of field B in All the rows
Filling first line
Try to add new row:
This is normal behavior or a failure in the last release???
