If they’re missing all here I think you should reinstall C9 from the full installer downloadable from your Steinberg Account.
Should be at Right Zone>Mediabay>Home>Loops and Samples (production grooves is also visible here but a bit lower down the line)
Mediabay (F5 on windows)
Production Groove also in GASE Load Preset. (or the Load tab on the full GA)
