Switched in Electrical Schematic but it reports that the electrical database is the wrong version. However now the Add-In dialog is not displaying any checkboxes and the buttons have lost their raised borders. The software has been reinstalled but it has just picked up how it was before. Both products version 2019.3.

Here is how it looks and how it should look like:

 It looks like a graphics problem, but how, why?

Any ideas how to recover this situation please?
