Some of my married Zois do not autonomously interact with each other at all.
Clicking an interaction from the interaction bag to force it always works. Clicking the Social need to auto-fill only works sometimes on certain married Zois, and autonomy only works sometimes on certain married Zois too.
For certain other Zois, the interactions automatically cancel when I click Social to auto-fill the motive, and they never interact autonomously.
UPDATE: I have solved the problem. I had the two affected Zois publicly announce they are a Loving Family by picking romantic interactions manually until the bar was maxed, and now they interact again!
