Defaul WPML Language Switcher accessibility issue

Hi,
I submitted my website to Google PageSpeed Insights and i get 3 accessibility issues regarding defaul WPML Language Switcher (the one that comes by default on Enfold main menu).

Here are the issues:

1. Elements with an ARIA role [role] that require child elements to contain a specific role [role] are missing some or all of these required child elements.
2. The name of the links is not distinguishable
3. List elements (<li>) are not contained within parent <ul>, <ol>, or <menu> elements.

These issues negatively impact overall PageSpeed score, preventing an effective website optimization.

Any help?
Thankyou
