Modal popup’s width from ‘ultimate addon for elementor’ breaks with polylang

Hello,

I’ve got a WordPress with both plugins :
– Polylang (free)
– Ultimate Add ons for elementor

You can look at my website at : https://horaires-bateau-arz.refdig.com/

The issue is :
– Blue buttons that are in Header & Footer are ? modal popups ?
– Without Polylang, the width of modal windows matches what I have set up in the builder (PC 500px ; Tablet 50% ; mobile 80%)
– With Polylang activated, this width parameter does not work

It seems that only PC width applies, on all screens … but finally not even this one works.

If the only solution is a bit of CSS, can you give me the good CSS selector ?

Thanks,
C?me RIPOCHE
