Getting Confused on Pawn Options In Character BP, Screenshot Available

I’m using Steam & Door Travel
I’m testing in both way:
1- Same PC
2- Two PC’s with Two Different Networks
within same pc i can join with 2 windows until Credit Level until here everything good, but the first player who will use the door the other player will travel with first player without using the door.
NOTE: each Level with different character BP and GameMode BP, but all of them Childs from Main BP. and when I make all Posses Player0 in all levels when second player join the Credit Level the first Player Freeze. Exactly same thing if I’ll test it in 2 PC’c with different networks.
