How do I stop the character player to slide?

Hi all,

I have a small scene with different platforms where the player needs to climb up by jumping on each platform. Each platform has a SOLID and also the player character moves all the time with the bullet behavior. When the Character jumps and touches the edge of the Platform he starts to slowly slide down, how do I prevent that?

I figure it out. Its the collision box of my character has some corners in it and they are getting stucked.
