DisplayLink extend the content and I do not see the second screen in settings>display

[LionelD]

Hello,

Before using the DisplayLink, I had my MacBook Air M2 2022 (used as "Main Screen") and a iiYama Screen (used as "Extended Display").
I bought the Display link and a second iiYama screen, exactly the same screen

I installed the DL package, I have now 3 screens working, my Mac with the main screen, and a duplicated extended screen on the 2 iiYama screens...
When I go in Screen > "Organize", I only see the Mac Screen, and one iiYama screen, named "PL2793H", the third screen in not here

Can somebody explain to me why? the real strange thing is that when I click top right on the mac double switch icon, I see the "duplicate screen" written, when I click on it I come back in the Organize menu, without have the duplicate option activated

Your help would be reaaaaaally appreciated!

Thnak you
