Please explain your issue is in as much detail as possible.
Decisions which require council approval feature an empty seat in the calculation.My character is a khanate at the kingdom level, so one additional advisior slot is available to be assigned. The voting however counts seven council members: six assigned ones and an empty seat. I am unable to fill this empty seat, which leaves a permanent vote against my decisions. I noticed this after my previous character died. I can't verify however if this occured before he died, as decisions were never challenged. I presume it started following the succession.

Steps to reproduce the issue.
Unsure. I noticed it following succession as none of my decisions could be enacted. Before succession it may have been present already.

I've seen that also in my games. I think it happens when you are in a regency and the regent is also a councillor (Chancellor, Marshal, Steward, Spymaster, Court Chaplain or one of the Advisors). The game gives him the vote for his job and doesn't take into account that he has another vote because he is also the Regent and list his regent vote as a missing character vote.
