Mystery properties

Hi All,

      I have a schematic that has extra properties that I did not add:

CONNWIDTH    8.000
HIGHLIGHT    NO
MAXWIDTH    8.000
MINWIDTH    8.000
NETGROUP    0
NETWEIGHT    50
PLANELAYERS    
RECONNTYPE    STD
ROUTELAYERS    
SPACINGBYLAYER    
TESTPOINT    NO

I did not add these properties and I think they are interfering with the properties that I do use:

MAX_TRACK_WIDTH    30
MIN_TRACK_WIDTH    30
REC_TRACK_WIDTH    30

I am using powernet to create a net list.  If I examine the netlist that is created the properties that I do want are not there for many of the nets.  For the nets that do not have these extra properties seem to be OK. I am using powernet V2.0b07 and Orcad version 16.6 s055

Thanks in advance.

Roger
