Problem statement appears below screen shots.






This same problem is happening with two different projects. I am trying to change their priority schemes. I have done this for other projects many times. For these two, the most recent two I have tried to change, they have ended up being listed under both priority schemes and I cannot remove them from either. When I go to project settings, they both show the old priority scheme that I am trying to remove them from.
Screen shots show that the project PST Simulation is appearing in both Priority Scheme with Blocker and PST Product Standard Priority Scheme. When I try to delete it from either scheme, I get the message "We couldn't update the scheme. Refresh the page and try again." Refreshing doesn't help. I have tried this on several days over the past two weeks.
Any ideas?
