Ability system doesn't work when posses a new character through character selection

I’m stuck into a problem that when I possess a character through character selection, ability system doesn’t work. When I set my character as default pawn, the ability system works perfectly fine such on activated, once the projectile hit the target, it applies the gameplay effects to them and destroys the projectile as I programmed it. But when I set my default pawn on game mode as none and try to possess character through character selection. the ability system doesn’t work like it doesn’t apply damage to the enemy, nor the enemy can damage me either. Is there a way to fix it for the character selection? Thank you
