Boxcollider 2D blocks world space canvas

Hi guys,
i have a problem which it seems i'am unable to solve.

• I'am developing a 2.5D point and click game. Point and click works with Box Collider 2D-s on the clickable surface, then ITween from Playmaker.
• I want to display a context menu with a world space canvas above it.

The problem is, that i cant click on the context menu. The collider picks up the raycast, and the character starts to move. On the other hand, if i turn of the collider, everything works fine.

 

Few minutes after i posted this, half of the problem already solved:
- If i block the BoxCollider's layer with the Blocking Mask on my Graphics raycaster, i can mouse over and click the context menu. It still doesnt block the rays tough - the character moves to the clicked point.

 

Second half of the Question also solved. I built into my Point&Click Playmaker system an action which checks if a menu was clicked. (Ecosystem, Is Pointer Over UI Object, Pointer id = -1)
