Question about Feller EDIZIOdue Smart Light Control for Philips Hue

The new Pro has recognised everything for me, including these buttons, and they work perfectly

I managed to migrate some existing Feller switches to my new Bridge Pro, but didn't install any new ones. When I try to add a Feller switch, the bridge doesn't find it (after pressing the button on the bottom right for 10 seconds).
Has anyone had the same problem?

Vielen Dank!
