!multiplayer characters problem!

Hi Guys,
I’ve a problem with multiplayer characters, To simulate Multiplayer Gameplay i am using internal UE4 setting (2 players in the map, run dedicated server, DON’T use single process) in practice when player receives an event as pick up a weapon or have damage this event is replicated in Player B ( for example Player A had 10HP damage, Player B had 10HP damage too), i have deduced that though i m running 2 different process the character is the same, i would like to know if i have to create a realy LOBBY-MATCHMAKING BP or if i’m doing wrong an option or a BP.
