That is most likely because of you spawned MP units (named as *_mp)
Use Control + Alt + 2 to toggle between spawn tables.
Set it to "Spawn hotkey source: Raw"
You can now press Control + Shift + F2 to view the spawn hotkey list again. Pick squads from the list that don't have the _mp ending in their name.
It was simple, actually. The game script spawns invulnerable armor. Used the toggle and destroyed them. к Родине!!
