Any luck reproducing this, Chuck?
I don't know if this means anything, but in a recent category containing 41 photos
, all but four photo pages display the extra field correctly. The 4 that display the extra field twice per page are photos 11, 21, 31, and 41. This might be significant because we process photos in groups of 10. So the problem photo pages listed above would be in the first position on each new page when uploading/processing the photos. (i.e., photos 1-10 are processed on a single upload photo page, then photo #11 is the first photo on the next upload photo page, photo #12 is the first photo on the next upload photo page, etc.)
