Can’t reach soulmates level

So my current household been sweethearts since high school and once they aged up I made them get married and have kids. They reached soulmates level once before but it went away and everytime I go play another family, I come back to them being strained. This time I’ve played them only and can’t seem to reach soulmates again.

I’ve tried everything including - maxing out both friendship and romantic - they are both attracted to each other - they have amazing compatibility - I’ve broken them up and maxed relationship bar again - I’ve moved them to different homes - I’ve renewed their vows - moved one sim out then back in - had one sim cheat to start relationship from beginning - multiple dates that reach gold

Nothing is working. My sims are even best friends and now both bars are full but profile says they’re just acquaintances.

I play for hours and hours and nothing. I moved them from 3 houses already because I saw somewhere to do that but What should I try next ? I hate not having them as soulmates.
