Strange connect iq warch face problem

Hello everyone 

it seems that I have a very strange problem with my connect iq. I am currently using a Fenix 7x pro. After installing two watchfaces they won't go away anymore. I have tried everything: reboot / every possible watch reset / app remove and installed again / garmin express remove. This very resilient little buggers are not showing up under the installed wf on the iq list but they are still on my watch.

Note aside: after every attempt to install for afterwards removing it, hoping to find the remove, was unsuccessful because there is no remove button!

Can anyone help me, please?

Thanks a lot in advance!

Best regards
