Character controller walking over colliders

Alright, so I have this bug as to where the player character is able to walk over certain colliders, mainly NPC colliders.

Certain colliders, such as the environment and some NPC's don't have this problem as seen in this GIF.

Why is that and how can I solve it?

Keep in mind that the NPC that I can walk over has a collider listed on another Layer titled Hitbox while the other NPC does not, could this be a problem? Also the environment I've listed as static so that solved that problem. The player character also has two colliders on him, one listed on the Hitbox layer as well in conjunction with his other regular collider, I'm not sure if having two colliders is necessary but I did that anyway just to be safe. I also have yet to create a Navmesh for the environment so that's not a problem at the moment.

This is my entire movement code for the player character. I'm also using a character controller for the player and a rigidbody for the NPC's.

Hi!

Have you managed to fix this?

I have almost exactly the same issue. I've tried changing slope limit, stepping offset, fiddled with Physics setting and nothing helped.

 

I've just updated Unity and it fixed itself. Not sure if it was just the Engine itself or something.
