There is no way that I'm aware of to do this currently, except maybe to use javascript/css to hide the messages that are placeholders (in this case it looks like you would have to use javascript because the only indicator that this message is moved is an element with the lia-fa-moved class which is inside of a td tag inside of the tr tag you would want to hide).
You could delete the placeholder messages when you find them if that is an option for you.
If you feel strongly that this is a product bug that should be fixed, I would recommend filing a support case.
