It looks like there is a problem with linked marriages.
Steps to reproduce:
1. choose person (A) that is already available in db
2. add new spouse (B)
3. go to new spouse (B) and create marriage event linked to first one (A)
Marriage event will not be linked to person A.
When you do the same but create marriage event in person A and link it to B it works OK.
Best regards,
Sebastian
