As I've mentioned before, generally in consumer related issues, a "2 for 1" offer is something that you enjoy - but this is not always the case, for Blogger blogs. This week, we have owners of private blogs, who report that their blogs, which previously displayed the "About Me" gadget, now show a "Contributors" gadget. The issue of the "About Me" gadget being replaced by the "Contributors" gadget is not arbitrary though.
If one looks at the unwanted "Contributors" gadget, one sees two members listed. Looking beneath the member links, at the URLs referenced, one sees that each link merely duplicates the other. As we know, for blogs which have multiple members, the "About Me" gadget automatically displays as "Contributors", and shows the member list in place of the single owner profile.
The problem here appears to be in the gadget itself. Looking at Settings - Permissions - "Blog Authors", only one entry - the owner - is displayed in the list. To date, this oddity has been reported only for private blogs. No odd duplication of links, in the Contributors gadgets on non private blogs, has been reported.
The good news here is that this problem is not difficult to resolve, on your own. While we wait for Blogger to correct the problem, you can take a few minutes, and make an "About Me" gadget that fulfills your needs far better than the default "About Me" gadget ever did.
