It's quite common that all squads in a match isn't shown in the frontlines menu. Seem like 50% of the time one squad is missing. Haven't noticed it being any particular squad or squadtype always that goes missing. I can't find the trigger for this bug.
Possible cause of the issues is that the missing squad has been made by a player in the match by the player going to the squad menu and from there creating a new squad by clicking on a empty squad space.
