Thanks for the reports, though it would be nice if you could also do a screenshot of the developer console and have it inspecting/debugging KC3 Kai panel.

In either case the issue has also been highlighted elsewhere, a bug report has been filed and apparently it has been addressed: https://github.com/KC3Kai/KC3Kai/issues/875

It should be fixed on v20.1
