the point is , i have a customized ribbon because there is an add-in tab with 4 buttons which call 4 different macro connected to the .dotm document... When i save the document the tab disappear, and when i click on one button, it's changing also the tab button (and 3 new button appears).
I would like to find where is this tab.

I've already make a new tab with customUI but it doesn't fit to what i want....
