Can not destroy Kingdom title

[mikemartinsen]

I can not destroy the title of Sweden.
One requirement says it can not be gavelkind.

It is agnatic-cognatic seniority, but the "not gavelkind" box is still x'ed out.

Is there some programming error or something?

Is your primary title gavelkind?

It is with the kingdom of Norway, that might be it then...
