[Police] help with sorting out demo cd's

Hi everyone. I have two different copies of the ghost in the studio demo cd. Both were given to me with different artwork. Both have the identical setlist. The weird thing is that they have different versions of the songs. Tracks 9-13 (the rare non released one) are the same however on both. One is also very clicky and poppy as if it was recorded from bad vinyl. Does anyone know anything about the story behind these? Thanks, Josh
