Multiplayer Movement

Good Day,

I still have a problem that my characters don´t “move” for the other player. They just hover over the ground.
Does somebody know this problem and can tell me how to fix this propably?

Could it be from my InputAxis?
I use them only in my CharacterBlueprint. Should I transfer my movement into my PlayerController or doesn´t it matter?

If you need explicit information just tell me and I give them to you.
