Thanks, folks. I did the power down and reboot, and now the USB shows more tracks than the HDD! See attached screenshot. When I have time I will try to find a way to compare with the Mac library, which is organized in a more "helpful" way than the easy to understand logic used by the B2. I will report back.
Ps- it's a Transcend 1TB SSD that has never given me any problems.
