When walking from a stair or slab onto grass path player is slowed/inmobile

Walking down from a slab/stair to a grass path works as normal but when going up from a path to stair/slab onto another path the player has to jump in order to move past that block. Particles are shown and the player is "stuck" when attempting to walk forward.

 

Hope the attached video works, if not it was simply of me demonstrating the bug.
