Sims being sent home from school/work when another leaves the lot

I own get to work/life and death and high school years which all have the "join" of "send alone" screen, whenever I leave the lot with another sim after selecting "send alone" with the one that goes to high school, they're instantly sent home after leaving the lot dropping their grade. When doing the same with the sim who works, they're instantly sent home after I leave the lot with another sim affecting their job performance
