Nevermind sorry! I found a way to remove the arrows on only both of my fieldgroups. I can share if anyone is interested.
A client called me about this today. First i had no idea what he was talking about until i hit one of the move buttons myself and knew what was the problem (even though I had no idea what to tell him why it was happening). Fortunately, I found the workaround posted above (thanks) so that he can at least keep working on his content.
So, the problem is with Gutenberg?
Is there maybe a way to disable the arrows temorarily until there is a “real fix” to this? I don’t want that he can accidentaly click on it again, because it happens way too easy.
