I was fooling around with some jersey files a few weeks back and I had the same problem. Hopefully it should work.

I have no idea why you guys are getting this problem. Andrew, your answer sounds good.
This is an interesting finding. Looking at your screenshot of the plugin, it is clear that the front and back numbers need recalculating. This also suggests the importance of these numbers, as they take primacy over individual jersey number placements.
In fact, this suggests that the front and back box information is used to recalculate other numbers when they are inconsistent.
