empty folder if setting a favorite to a custom menu

I seriously don't understand what's wrong. It used to work and a while ago i have added many other favorites to custom menu but now i'm getting an empty folder.

So i have a favorite that basically just opens a folder to list the files

<favourite name="VIDEOS - CLIPS">ActivateWindow(10025,&quot;X:\\VIDEOS - CLIPS\\&quot</favourite>

When i go to XBMC favorite menu and select this favorite shortcut, it works perfectly and xbmc opens a window to list the files

But as soon as i make a custom menu with this favorite, here's what i get:


This is not a problem with my favorite. The path is correct and like i said when i go to the "favorites" menu and select it then it will work perfectly. It just doesn't work when i put it on a custom menu...

What's wrong ?
