I'm sure there is something really basic that I'm getting wrong, but I can't figure it out, so I'm hoping some kind person will take pity on a techno-numpty, please.

I have a Kindle 3, and have been downloading books both from Amazon and from the Mobile Read library. I've installed Calibre, and successfully changed the metadata on some books where necessary. But two keep defeating me: Hunger, by Kurt Hamsun, and Enchanted April, by Elizabeth von Arnim. The names of these books show as "Arnim_Enchanted April" and "Hamsun_Hunger", so the Kindle sticks them at the end of the alphabetical list and won't sort them.

First I tried changing the names of the PRC files themselves and then transferring the new version to the Kindle. No luck.

Then, after installing Calibre, I edited the metadata for both books. They show up exactly as they should in Calibre, but again, when I transfer the renamed version to the Kindle, nothing has changed. This is driving me a tiny bit nuts now, so I hope someone can sort me out. Apologies for being longwinded as well as (probably) daft!
