Problems with some net's being split in two, on KiCad net list read, by adding / to net name

[lachlanA]

When KiCad pcbnew reads the net list it some time's split's the net's by adding / to the net, and not other part's of same the net, Example, GND will be split, with say the fill's still having GND net list name and pad's having /GND, not sure why yet. Or what I'm doing wrong to make this happen.
