Scouting problem

I had my chief scout handling scouting assignments and I thought it was working fine, but then I created a couple of new assignments (find me a first team striker, etc.) and I noticed they're never getting handled. They just sit there with a "preparing" status and never go through. I can't even remove them because it says my chief scout handles scouting assignments.

Is scouting an all or nothing thing? Either I set all the assignments or I have no control at all and the assignments I create don't get done?
