Preview Tab not appearing on Upgraded version

Hi, I’ve upgraded my Dolibarr 3.3.2 to 3.5.2 (upgrade page : 3.3.2 -> 3.4 -> 3.5.2)
And I don’t see the “Use preview tab” option in Setup Display.
I’ve installed a fresh copy of 3.5.2 on another folder for another of my companies … and it appears.
The upgrade and fresh installation files were the same.
Can someone help me on that issue ?

To have option preview enabled, you must check that module imagick is available on your php.
