Problem with extension CMSMasters Mega Menu

Hi, I have a display problem with CMSMasters Mega Menu extension.

When I want to change the options of my menu, I have automatically the color selector that appears. Even for an option that doesn’t concern by color. see picture 1.

Then when I select a color and I save, the chosen color hides all the menu options and I can’t do anything. see picture 2.

Do you have an idea ?

thank you very much
