Hi, first I tried to ask the WPML support for this issue but they confirmed is a setting in the Uber menu so here I am.
It’s just the flags on my main menu. They are set as dropdown to save space (website is www.mysardiniaholidays.com on my other website I also have them but not a Uber menu and so I don’t have the issue)
I show you what I mean: 
The dropdown menu goes to a large row and there must be some setting I can change just for the flags to make them normal drop down. I checked the whole main settings but there is a lot that can be customizable and I have no idea how (without messing up the whole menu)
Thanks in advance for your help
I swear I tried everything I could think of, thank you so much!
