Isabel Tatton - Same-Name Sister?

I'm the user who dropped the "concerns" sections in their profiles. I did not find anything revealing two Tatton sisters named Isabel when I dug for Tatton family sources, so I suspect that it's an error. I didn't exhaustively research the issue at that time because I couldn't allocate the extra time for it - I was merely trying to do a relatively quick reconciliation of the Tatton tree at that time. The former Isabel seems spurious to me - the Tatton family was seated in Cheshire and apparently didn't spread to other ceremonial counties until after the 16th century.

Thanks, John, I'll go with the conclusion it's an error.

John, there are more problems with this line. Geni says that i am a GGD of both Isabels. When i follow these lines, i find an Elizabeth Enield on one line & an Elizabetha Enfield on the other.

Going back further, there are 2 Elizabeth Enfields - one showing as the daughter of Hugh Bigod & one with no parents. So, obviously, a number of duplicates.

I'm sending this from my phone, so can't link...Sorry!
