Attention Curators, Please Help

I have already written once, and I understand that the links are not static as far as relationships to other people outside of a proven tree, but not THIS:

I added my tree, and when I first added it, my 4th great-grandparents both showed as my 4th great-grandparents. They are first cousins, and they both have the same biological last name. Three or Four Months later. My 4th great-grandmother still showed as my 4th great-grandmother and her parents as my 5th, but my 4th Great-grandfather is showing as my great Uncle and his parents (who are my 5th great-grandparents, are showing as my 6th great uncle instead of as my 5th Great Grandfather). What happened? I asked about this once three or four years ago, thinking this would work itself out, but it has not.

Here are the links:

Several children intermarried in both the May and Gibson line and now Geni decided that they are uncles and aunts instead of great-grandparents even though all of the links are intact:

Hugh May: Hugh May (My 4th Great-Grandfather, says he is my 1st cousin, 6 times removed), but his wife is correct, says she is my 4th Great-Grandmother.

Bennett May: Bennett May (My 5th Great-Grandfather, says he is my 6th Great Uncle) and his wife: Nancy Gibson May (My 5th Great-Grandmother, says she is my second cousin five times removed's wife's second great aunt.)

His parents are correct only because Hugh May shares a grandfather with his wife Malinda. But Nancy Gibson May's parents who are my 6th Great-Grandparents are showing up as: second cousin five times removed's wife's second great grandfather.)

Should I just delete them all, start all over or what?

I can't refer people to come over here from other sites, if it is not correct!

I look forward to hearing from you.
