I have found a few of these. If you look at the Info box to find the 'ref name=' you can search for that name to find the usages
* It looks like the '2nd' ref name usage should have the ending slash, but it is missing, so it looks like it is a new 'definition' of the ref name, using biography. Using the Enhanced Text Editor will probably help to see these.
* Format of the '2nd' ref name is incorrect at the end, ie '>/>', instead of '/>'
Kay, I sent you a message because I figured out yours, which was the 2nd one above.
