Someone has merged a couple of profiles resulting in an error (or a couple) in the family tree.
As I have understood merges are irreversible. This person now appears as his own grandson, and is married to family members whom aren't his wives.
How can this be resolved and 'restored'?
Are these public or private profiles?
If they are public profiles then please post a links to the person who appears as his own grandson. Also indicate who his actual spouse is as well as the names of the wrong spouses.
If you aren't sure what I mean by "public" profiles or what I mean by posting a link just respond and I'll give you fuller directions.
