If you have a Facebook friend w/ your same name, strange things happen ...

One of my Facebook friends is someone with my same name (he friended me out of curiousity, I guess). I enabled Facebook syncing in Contacts, and now some of his information appears on my card, including his job, Facebook email, URL, and Facebook IM address, and I can't get rid of it.

There was also separate card that had only my Facebook info, not the full set on my normal card (it must have been created when I enabled Facebook syncing). I thought maybe merging the cards would force Contacts to make me pick one or the other set of Facebook info, but instead, my single card now have two sets of Facebook info for two different people. There is no way to delete or even hide the bad Facebook info.

I could probably change my name in Facebook to my full first name, so that there would be two distinct people there, but no one uses that name and it seems overkill to make that change because Contacts isn't matching on enough fields.

And, when one of my family calls me from home, the other guy's face appears on my iPhone screen, although that's not the image associated w/ my card in either iOS or OS X Contacts. It's odd seeing that, to say the least.

This is in 10.8.2 and iOS 6.

If anyone has any suggestions, let me know!
