How do you make a sprite switch from 8 direction to Platform

I want my sprite to change from 8 direction movements to platform movements. I have made it so that in one instance 8 direction get disabled and platform get enabled. The sprite is set to platform simulate control left when it is on screen. So it should directly move to the left when the platform behavior get enabled if is on screen. But it doesn't. It just stops moving. How do you make it work?

Without seeing your capx it would be guessing, but could the sprite be overlapping a solid?

I created a test-capx and it works as expected when I make it, so there must be an issue in your capx..
