Rapture Pro does not import SFZ from proper legacy path

I have the Galbanum Piscis Rapture expansion pack.
I installed Rapture Pro today and tried to load a patch from that.
While it shows up on the browser, the patch does not load.
 
I started Sysinternals ProcMon to trace what is happening.
 
To start, Rapture Pro is running on an instrument track in Sonar Platinum. No other tracks. 
Load from Rapture (legacy) Expansion Pack:
Galbanum Piscis
0 - Bonus Pads
Actiniaria Pad
 
The following SFZ file is needed, located on my machine at:
K:\Cakewalk\Rapture\Content\Multisamples\Galbanum Architecture\SFZ MultiSamples\Spectrum Instruments\Gaussian Spectrum\GSP046 (FM2 01 07 01.00).sfz
 
This file is not located anywhere else. That is, it isn't in the Rapture Pro multisamples folder.

Procmon reports Sonar looks in:
K:\Cakewalk\Rapture Pro\Rapture Pro\Multisamples\Spectrum Instruments\Gaussian Spectrums\
and
C:\library\audio\plug-ins\rapture content\galbanum architecture\sfz multisamples\spectrum instruments\gaussian spectrums\gsp046 (fm2 01 07 01.00).sfz
 
The path in the K: volume is not correct.
 
The path searched in the c:\library... link is more correct, but where on earth does it get that?
 
So I make a symlink to the proper path:
 
In Cmd.exe:
 
a) create path "C:\library\audio\plug-ins"
 
Then type:

C:\library\audio\plug-ins>mklink /d "rapture content" "K:\Cakewalk\Rapture\Content\Multisamples"
symbolic link created for rapture content <<===>> K:\Cakewalk\Rapture\Content\Multisamples
 
So now I have a path to:
C:\library\audio\plug-ins\rapture content\galbanum architecture\sfz multisamples\spectrum instruments\gaussian spectrums\gsp046 (fm2 01 07 01.00).sfz
 
Now when I load the patch it works OK.
 
That's bizarre.
