Smooth crouch transition falling into floor.

I’ve made a smooth crouch transition blueprint as i don’t want the instant crouch that comes built in with UE4. The height adjusts back and forth correctly using an Finterp while i’m moving the character around but i’m having trouble stopping the capsule from falling halfway into the floor when ‘uncrouching’ whilst standing still. i’m guessing i need to set its location somehow to be on the floor (half its halfheight) but what i’ve tried so far hasn’t worked. Has anyone else done something like this in blueprint that i could look at? thanks.
