We're using Django Material (MaterializeCSS as CSS framework) on a new project we are building, and we got an issue with a language selector in the admin navbar. The issue is happening on Firefox, not on Chrome, and I couldn't find what's causing this. Can you check it please? The URL is: https://accountant.swapps.io.

Here is how it looks for reference.

The templates doesn't have a lot, and the CSS for this is minimal but I can provide code if needed. Thanks!
