That is actually VERY simple.

1. Few native Poser figures are symmetrical. (Rex and Roxie being the only ones I know of.)

2. Not all Poser figures are fully welded. Posette, Sydney, even Lo Res Alyson have welding problems.

3. Morph brush Symmetry ONLY works when the figure is in its "T" pose.
   But this last statement depends on a LOT of things, so play it safe and use it ONLY when the figures are in their FULL ZERO DEFAULT "T" Pose.

I never use a "V" or Dawn, so forgive me for not knowing how they behave (or not).

4. Want to do figure object file work?
   Load the object file in BLENDER. (never use an object file that you exported from Poser)
   Use the default object file after you unzipped the obz into an obj.

Do you object file work in Blender. (Morphing, sculpting, do NOT add or delete any vertex, or you can start over.) => Do not forget to set the "X" Mirror for both, edit and sculpt, before starting. LOL.

Then use a fresh cr2, and set the 2 lines to point to your new object file.
Or load YOUR modified object file from Blender as a FBM in PoserPro.
