DZ09 smartwatch how to use installed apps ?

Hi, i've just installed .vxp apps on my smartwatch, but their icons aren't visible on the homepage, so i go to options > shorcuts manager, and the apps appear but when i click them (the only thing i can do) it says that i cant activate the shortcut because ive reached the maximum limit... the problem is, i can't disable shortcuts that are actually visible (same text and no more options) ! so, if anyone know how to do it or at least how to launch my apps, i will be happy to ear that ^^

(Sorry for the English, i'm french)
