If you are using mods that’s likely the cause, many mods such as MCCC will change the roles of NPC Sims (depending on settings), essentially any mod that changes how townies behave. You may want to test on a mod free new save, and remember to delete the localthumbcache file from your TS4 folder after removing mods.
@Kita5399I understand that. However, MCCC has a specific module, "careers", that creates roles/new jobs for sims and I do not have that module in my game for that very reason. In the past, that specific module kept giving my played sims careers so I removed it. Since then, I have never used it and have never had sims or seen sims get put into careers at random once it was removed. This was years ago but I did update all my mods so I will test.
