When choosing any widget, there are problems with styles (screen 1,2,3). Tried to include a dark theme and by default. This does not seem to be a particular site problem, but a general Swiss knife. Check, please.
If you turn off the Swiss knife, then everything is OK (screen 4)
Can you please provide website details so we can inspect.
Please type website login into Website credentials field
I have created a test site. The problem on it is also in the default installation. It can be seen by turning the swis knife on or off
Removed sensitive date and managed to see it.
Thanks. Will add it in the next release
