Projection issues for rc.4 and rc.5 releases

So I'm getting a weird issue with v rc.4 where it's writing the horizontal units for Albers SHG as 'metre', as opposed to 'Meters', as previous versions have done.

The problem is, when using this precipitation DSS into HEC-RAS, it hits a runtime error from PROJ complaining about an invalid linear unit, as shown at the bottom of this issue. I'm not sure how PROJ has an issue with 'metre', but it causes this issue.

So I upgraded to the new v rc.5 to try again, and now the Importer example Jython script stopped working:
type object 'mil.army.usace.hec.vortex.geo.WktFactory' has no attribute 'shg'

This is the PROJ error when using the rc.4 'metre' DSS:

Start with the linked Importer example Jython script and its WktFactory.shg call, then reproduce the rc.4 PROJ unit-conversion failure and the rc.5 missing-attribute failure. Done means the importer works with the release projection data and PROJ accepts the generated coordinate systems without the reported errors.
