Extra Lines Roster Bug (With Video Link)

BUG LINK:
https://www.xbox.com/play/media/NTc3rx5nMD 

While editing my Rosters, in my attempt to assign and switch Roles, the Boxed 'Roster Grid' would switch from Showing 4 Players to only 1 Player, or 3 Players to Only 1 Player.
Sometimes it would show just a jumbled box, with multiple Players names overlapped, which seems like a Coding error. (as if the codes are all mistakenly assigned to 1 box)

The temporary fix would be to switch back and forth between another line, then when switching back to the Bugging Line, My changes would appear. 

This would happen to me when using the New Jersey Devils in Online Versus. 

This Link shows the Roster Bug in the 1st, 2nd and 3rd EXTRA LINES, doing exactly what I said before! 

I noticed this when resetting my rosters after the update!

(I posted about this bug before, but could not get a video because my 10 Hour Trial was Over, and then I forgot exactly where the bug was!)
