Hi @Bee9908
These 2 'problem families' could you explain the family connection of them, I have had similar issues once but worked out the families were related as in (all siblings) or similar.
Let me know if you still need help

I have no connection to EA
@Bee9908 Just checking the process you're using to edit them..
Are you using cas.fulleditmode as in > 'testingcheats true [on]' > 'cas.fulleditmode' Click Sim while holding shift > Clicked 'Edit in CAS' ?
Also, are they Adults, and do you use any mods or cc?
In the image below is what I have (with only 1 adult in the lot) when 'hovering over the sim' there are no other....

I still need to know your first steps, if it's Gallery to Cas to 'find and put in a household you don't need' cas.fulleditmode on anyway, but you do need to put in testingcheats true or testingcheats on for them to work
Confusing @Bee9908 your title says add a parent and your post says add a child, so adding a child you have to click on the parent (not the child like your picture shows) to add a parent / another sim from the gallery you just click the gallery and 'merge' then add the 'connection'
Are you trying to add a connection of sims in the household already, (?) I get that but your picture is showing the child, you have to click on the adults and make the correct connection there: via the adults, not the child, ie: connect the adults first
