Watch reboots when trying 'Add New' in the Watch face menu

On my FR 945 LTE (not in the Connect app), when i choose Watch Face and scroll down, I can choose 'Add New'.

Then I get the option of a digital and analog clock. So I pick one.

But then a downloaded watch face appears, with the menu (Layout, Data, Accent color etc.). When trying to select one of those options, the watch reboots.

Is this a known bug? (and is it going to be fixed?)
