Problems setting relationships in CAS

I have a large legacy family I remade for The Sims 4. The family consists of three YA siblings, their spouses and one sibling's teen son.

In the CAS demo, I made all the YA and set their relationships fine with no problems but when I added the teenager to the household in CAS when I got the full game, I had issues setting his relationship with his father (his father's wife is not his biological mother). The father's relationship list on the side showed his son as being his son, but the son's showed his father as being a roommate and it would not change when I tried to set it to father.

Eventually I gave up and moved the household into Oasis Springs. I looked at the relationship panel for the father and somehow, his son was showing up as his brother. I evicted the family, pulled my saved copy of them back out in CAS and tried to redo the relationships. This time, I couldn't set the father's relationship with his sisters. Same issue as before where I would click on Sister but it would stay as Roommate.

I'm really frustrated because there's no way I can play a legacy challenge with relationship issues like this. Any help or suggestions would be most welcome. This is the first serious problem I've run into with the game. I've been playing almost 24/7 since September 2nd and it runs beautifully with no serious bugs but this one is serious and I just ran into the problem today.

I kept running into the message 'can't edit a previously made Sim'. That was truly frustrating and very close to what you're talking about. I solved my issue by taking the household into cas.fulleditmode and from there I saved them to My Library (see the folder on the top right in CAS). Then I clicked on new family in my game save and added them anew, placing them back in their previous lot. Took them back into cas.fulleditmode and I was able to reset their relationships. Hope this helps.
