Collision Help

hello
Use these pictures as refrence Collision Errors - Album on Imgur

In Short the default player sphere is the only collision thing that works, even if i add a separate collision box it still doesn’t collide. As you can see the mesh’s collision is convex and before it was a basic box.

ALL Actors, meshes, etc in game have collision set to block all
This happens in all levels
How can i fix this
