I need help with stage collision editing

[britipinojeff]

I was editing a platform on a stage and I created a ledge for it and a wall right underneath where the ledges are. In game I can't grab the ledge. I later tried moving the wall a little bit away from the ledge so that the ledge kinda sticks out from it, but I still couldn't grab onto it. Is there something else I need to do?
Also I am trying to add a animated platform to another stage, but when I load up the game the collision for the platform doesn't appear where I placed it, instead it is high above the stage and doesn't move with the model animation. In BrawlBox it appears to be fine though.
