fix: 2 errors with the same text

[kenny-not-dead]

close #5972

When trying to fix the bug, given that we had previously used a check for the presence of an error message in this cell by key, I wondered if this was necessary. So, two different errors would generally be shown in one cell, and given that we had already encountered two errors with the same text, it seemed appropriate to me.

In fact, I think that this problem, or rather the clearing of other error messages, still requires attention, perhaps they should be cleared when a new one appears... but this is a subject for another discussion
