Hello @Someone07 !

Every menu item in list has the CSS styles like

li class="bx-menu-item fi bx-def-round-corners bx-def-color-bg-hl-hover bx-stl-mil-wo-gaps group"

where bold element "fi" is added form the language info. So for English it would be en, for the German - de etc. Same addon exists for the a link within:

But you have the defined parameters for the .fi class and it drops the fine drawing of this language menu item:

both points don't exist in the default UNA package.
