When you change something about a spousal relationship it resets the marital status to married when the constituent is still widowed (or whatever status was previously)
We’re currently evaluating this issue for a fix in a future patch or service pack.
Steps to Duplicate
Precondition: Life changes are configured as follows: Deceasing > Global rules for deceased constituents > If spouse exists, change marital status to Married. Marriage > Global rules for married constituents > change marital status to Widowed
Steps to duplicate:
1. Constituents > Add an individual 2. Enter last name, first name, marital status > select Household tab and add a spouse relationship, select Spouse for both relationships and leave the checkboxes marked > Save the record 3. Go to the spousal record and mark them deceased 4. Go back to the "main" record and edit the relationship to the deceased spouse > change something about the record (start date, end date, relationship type, reciprocal type, etc) 5. Review the martial status to notice it updated to Married
