[Koha] Paid For Question

I have a question about the paid for notation on the item record. If you see here: http://screencast.com/t/AKOcYNiPBy3n it says that it was paid for by a patron on the 24th of Sept. Then if you look at the patron's record http://screencast.com/t/UzKqgaPayou see that they did make a payment related to that item, but it wasn't a payment for the lost item - it was a processing fee. I'm wondering what makes this note appear in the first place? Thanks Nicole
