2 Problems with the Current Event

I have 2 anoyinng Problems  with the current event.

First: I cant disaband all my Team Members, the game only let me choose 5 Members when i tried to swap the last Unit it just hides the rest of my units i have in my list, i dont wanna keep my old team, and fight with a missing unit how to fix this?

The second Problem: I only can choose 5 Units in the crisis quests, which means i cant even place my team just 1 Unit, and the rest of the four places i use for my allies.

Both Conditions are quit unfair, and make it even hard to battle fair and straight, how do i solve this?

1. You are only allow 120 DC (Deploy Cost) total for your team. You probably are very close to 120 DC after you changed the first 5 units and your last unit probably a low DC unit, that's why you can't switch it to a higher DC unit.

2. I don't see anything wrong with that. You can use any combination ranging from all 5 units from your own to 4 ally units + 1 of your own unit. They tried to make the crisis quest difficult, that's why they don't give you all the deployment spots you need.

120 Dc?what does Dc mean?
I picked 3 6* and the rest are 5* but i am quite disspointed if it is written there it is allowed to place 6 Members i dont think its fair to leave the last unit out because the team is getting to strong, i still had troubles with the last crimson quest, i wouldnt have that trouble if i could used the allowed units as the games told me right in the beginning, and another user is haveing the same problem as me he posted it on facebook.

DC = deployment cost... every unit has its own DC, i think the higher rarity (6/7*) tends to have bigger DC requirement.

Oh ok now i see thanks for explaining it.
