can’t edit Tabs when there are many

i’ve made a Quadmenu Tabs menu that i need to have about 12 tabs. the problem is in the backend, and horizontal scrolling. after adding the seventh or eighth tab the Settings gear all the way to the right of the tabs titles is out of view off canvas. i’ve got the horizontal scrollbar at the bottom, but it doesn’t go far enough to the right to be able to click the Settings gear icon to edit the tab title and other settings. i can’t think of any way to fix this, and have tried it in different browsers. could you have a look at this please? it’s sort of urgent!
