About removing the active language’s flag, you couldn’t find an option for this because strangely WPML doesn’t have this as a feature.
I have added the necessary custom css to hide the flag using:
loading the .mo file needed to define the translation domain name which was “circleflip”
**Please share the French .mo if you feel like, it would surely help other users.
you now have the flag displayed on every page, except now it will not show on the blog, we’re still working on it, and will update you as soon as we fix it.
