[MC-125781] /data won't work with more than one entity and selectors keep adding , or ] with each tab press

For some reason i can't make the data command modify all armor stands instead it tells me the "Only one entity is allowed, but the provided selector allows more than one at position 0:

Also if i try to use any selectors in a command like @e[type=Zombie] the auto complete tab will keep telling me to add (,) or (]) to the command infinitely this makes it so i can't use the tab auto complete after i finish writing the selector and attemping to up arrow through previous commands also fails.

There is no crash when it occurs

The environment field is supposed to contain PC details (if necessary). You left the issue description empty, so the bot thought something was missing.

Apart from that, this has already been reported here: MC-121807

I didin't mean to do that i didn't see the description part in the box should scroll down more often.
