Yealink CTP18 not showing any contacts in "Meet Now" tab

Hi,

Having issues with a Yealink CTP18 (zoom meeting tablet) that is connected to a Yealink MeetingBar. Previously the contacts appeared fine but since yesterday no contacts are showing but I can search for them still.

What settings would effect what contacts are displayed/previewed in this tab? Any help is appreciated 🙂
