Hexxit Map Problem

[WarmAndFuzzy]

My problem I'm having is with the map. When I delete a hexxit personal server and make a new one, it somehow remembers the old map, and sticks the new map over that one, but I can still see parts of the old ones. Here's a dandy picture for you to examine so you can better understand what is happening. Any help would greatly appreciated.
