This thread is resolved. Here is a description of the problem and solution.
Problem: The client is trying to reduce the space between flags in the dropdown menu of the language switcher.
Solution: If you're experiencing excessive space between flags in your language switcher's dropdown menu, we recommend trying the following CSS code. Navigate to Appearance > Customizer > Custom CSS and add:
.wpml-ls-menu-item ul.sub-menu a {padding-top: 0px !important; padding-bottom: 0px !important;}
This code should remove the padding from the top and bottom of the flags, bringing them closer together. For more information on how to use CSS and the padding property, you can visit https://www.w3schools.com/css/css_padding.asp.

To overwrite that behavior, please go to Appearance > Customizer > Custom CSS > Add the following code and save:
