Perspective Multistate buttons border radius

I'm using a multistate button in perspective and i'm using the border radius to round the corners.
The middle button is how i want it to look, but the top and bottom still have square corners, even when i set it to radius.
Is there away of fixing this?

Thank you Paul

My guess would be: Your style is being overridden by specific properties.

Try setting this to the same value (or bind one to the other).

Thank you, that was what the problem.
