HELP: Collide with objects that are moveable?

Armuel

The player in my game perfectly collides with walls that have moveable unchecked. I want that same collision between an object with moveable checked, an enemy. Despite using the collide behaviour, the player slightly pushes the enemy around upon contact. How do I fix this?

Make the bounciness of one of the enemy greater so that it knocks back further.
