Yes, you will have 2 or three files of this kind to delete.
Just delete it.
C:\Users\Matjaž\.ancestris\13\config\Preferences\ancestris\modules\editors\ancestris-modules-editors-genealogyeditor-table.properties
Do the same for the next errors.
You also can delete all the "Preferences" directory, but you will lose all your preferences of the software, which is not the most user-friendly mechanism.
So, I recommend to delete file by file.
