[APP][Pro] Device Capabilities - Enhance the capabilities of devices

Hi all,
im new to Homey so im not sure where to post this, here or in Bitbucket. If this is the wrong place please tell me.
I want to create a virtual device with Device Capabilities but my changes are not being saved. When im setting the device class and click save, the field is empty again when I click on repair again. When im adding a number field and want to enter a BLL expression the BLL expression field is greyed out and I can’t enter anything. When I press “save device” I can see a saving message for less than a half second maybe, but nothing is being saved.
I tried to restart Homey, did an uninstall and install of the app, tried Safari and Brave as browsers, tried from the webgui and from app on iOS, no success. I have no clue what to do.
Am I doing something wrong?

I forgot: Im on Homey SHS

Edit again: Its working now. The Better Logic Library hat somehow a problem. When looking into the settings I got timeout popups. I did restart the app, then everything was working. Strange for me is im stopping the docker container every night for backup, so I thought there is a fresh start always.

Happy eastern
