Can't hide the title or menu bars

Messenger Support

For some reason, the option to hide the title and menu bars is missing for me, but somehow visible for a contact of mine using the exact same version. I tried wiping the Messenger settings, but this did nothing. What’s going on??

Messenger version: Windows Live Messenger v8.5.1302.1018

Windows version: Windows 10 v1709
