Solved My worldguard is not allowing me to push pistons

Im working on a parkour map but for that i wanna use pistons or redstone in general...

While the server that parkour is running on also uses griefprevention for skygrid its not griefprevention disallowing it and accually worldguard not cooperating, as soon as i turn off worldguard it works the piston push retract etc. but as soon as i turn wg back on they wont do so anymore...no idea why
