I feared that may be the case. This game has no in-game instruction and finding reliable info online is also very difficult. It really begs the question why there is no in-game display of your unbuffed party strength.
Thank you for taking some time to educate me.
I just get so depressed when I don't have friends and the game is offering me squads like this...
Best way is to go on the discord via the in game link

Although it doesn't display their full power your helpers still function at full power, so it's not as bad as it seems.

Nothing wrong with those helper squads you posted. They will beat most boss groups.
