CDJ 2000nxs2 Untag Removes Cue

Playing on linked CDJ 2000nxs2 players through USB/SD Cards loaded through Rekordbox 5.

When untagging a song while the song is playing, the untag button removes the cue and turns the light out. If there is a loop playing and I untag the song, it releases the loop. Occasionally, untagging one player will make other players lose their cues too.

This doesn't happen every time, but easily over 50% of the time

Any help? Cheers!
