Safari Plugin Shows in Dark Mode only

This question was asked in German but I have found that when clipping in Safari (Catalina), the dialog box is in dark mode and one cannot read the text.
How can this be changed?
I am running version 3.01 of the Clip to Devonthink and my version of Devonthink Pro 3 is 3.02.
The same thing occurs in Chrome.

Could you please post a screenshot of the clipper plus one of Preferences > Sorter? Thanks.

Here is the other screen shot

Thank you. Do you use Mojave or Catalina?

Catalina but I think it did it in Mojave as well
