This also happens with a Self-Employed Sim who takes an odd job. As soon as the odd job is finished, the career panel goes completely blank, with the custom self-employed text gone. If I take a regular job, the career will show up, but as soon as I quit the career, the career panel is completely blank again. Tested on a vanilla save with a brand new Sim. I can try to re-register the odd job, but the panel remains blank.
As long as they don't take odd jobs, Self Employed Sims are fine, the custom description shows up properly.
Sorry, I know this is a slightly different issue, but it's so similar that I thought I would post it here. I hope that's all right.
