I can’t cancel my Sim’s acting gig that has already been but won’t go away

I have this problem too, I accidentally canceled the pop-up of my Sim going to the casting so it said she failed and didn't get the role, but in the job window the time for the casting stayed. I can't cancel the gig and changing agencies doesn't do anything either. Even after leaving the acting career and starting it again she's still stuck with the same gig.

Guess that was it for my Sim's great acting career....
