OPM using PDS spec's with Inch units the Diameter is incorrect (Mixed Metric Project)

Using the existing OPModeler_MMetric project and pointing to PDS specs (settings below), OPM will successfully place components from the specs into the model, but are not scaled 25.4 x so the diameter is incorrect.

If I use the OPModeler_Imperial project the components are placed correctly, but I need the file to be Mixed Metric due to the the existing 3D models from PDS being drawn in Metric.

Settings

Using the existing OPModeler_MMetric, changed the following in the PCF file

OPM_SPECPLUGIN_CURRENTSOURCE = PDX

OPM_SPECPLUGIN_OPM_DIM_CONVERSIONFACTOR = 25.4

OPM_SPECPLUGIN_PDX_PCDDIR = C:/PDS/pd/rdbu/specs/

OPM_SPECPLUGIN_PDX_LIBDIR = C:/PDS/pd/rdbu/lib/

Thanks
