They might be? I'm not sure if there's a way to reset the family. Other than to take each of them into CAS, save them. Add each of the newly saved Sims to the family and save them to the library. Then in a test-save have them travel to Oasis Landing.
If you do that, it will erase all skills, job, relationship outside of the family. However if it works, you can edit those things via MasterController if desired. Or go back to original family and further troubleshoot them.

This reminds me of one of my Sims that had nearly all skills mastered. That I wanted to have her master and she some how glitched. I was heart broken. I was going for my own perfect Sim.
I had pulled her into Create a Sim previously, so I had a copy of her. I ended up deleting the glitched version and starting her over. It seemed to work out for the better that I did that.
