Sims auto aging up

As soon as I join my save file, all my sims are fully aging up even though it is not their birthday. I tried uninstalling, reinstalling, restarting the game and every time I play the save file they still are aging up. I am unsure of how to get them back to their normal state before it occurs. I will state my game is on long life span, however I changed it to normal and they were still aging up. I am unsure how to prevent this or how to revert it back to normal. I also have CC installed and got rid of any bad cc that I could, I also am playing from the Pc. Any help would be appreciated :)
