Mobile Version of my site // language problems on nav // WPML

Hello all, I have such an annoying problem I am trying to fix

I have a WordPress site, it uses WPML as I have 3 languages on it – EN DE and FR

The main site/desktop version is fine

I recently did some modifications to the site so it works fine on mobile devices. It is moreless working fine now on mobile but I have a small problem

URL = https://www.kingkarel.com

When I go on the site with my iPhone – I change it to the DE version, then I press NAVIGATION

In the NAVIGATION, I just want to rename 3 of the words that appear in the iPhone navigation scroller that appears

So I go to the WP-ADMIN, I go to APPEARANCE > MENU > MAIN NAVIGATION – Make sure I am on the german version and simply rename the 3 “pages” I want to rename to the write word, save it

But whatever I do, it’s not changing when I access it again on my phone – I have cleared browser cache and everything, tried on different device but it doesn’t change

Using WPML settings in my WP-ADMIN I even synced the menu but no luck

Can someone please advise me here?
