Weird Slicing - No raft

so... to "solve" my raftless printing problem, I just adjusted the Z axis so it wasn't stopping the flow on the first layer...

but now, I'm noticing, the first layer of the slices where printing is done (Skeinforge)  on the printer, is some randomlayer from later in the print...

the only difference between my rafted print, and the un-rafted when i slice it, is wether or not the "activate raft" option is selected...
but for some reason, when I de-select the option, i get this weird "pre print" layer from somewhere in the run, inserted as basically a raft layer...

according to the Pronterface print window, it's the 5mm layer, but it's being done before the .2mm layer...
