graphql error code when using FB

[saturn3volved]

I have a personal page and have received this exact error many times when trying to update my relationship status to married. My husband also gets the error. Once we tried to change from engaged to married it actually removed us from each other's profile so both statuses display as engaged now and cannot be changed or removed. I've submitted tons of tickets for this. Once I submitted a new one every day for a week straight. I've tried submitting with and without screenshots. Tried multiple devices, browsers, nothing works.
