Rather than use Stylepicker to determine the missing basses, have you gone into Realtrack picker to see whether or not the Realtracks are actually present? (There might be a glitch in Stylepicker that's giving wrong information.)

A simple sort by "Set" would make it easy to identify them. (see below graphic)

From the below Realtrack information, the folders you need to look for (Set 14) under \bb\Realtracks are called...

Bass, Acoustic, Jazz, Half, Quarter Sw 140
(this is #2128)

Bass, Acoustic, Jazz, Half, Half Sw 140
(this is #2129)

Bass, Acoustic, Jazz, Quarter, Quarter Sw 140
(this is #2130)
