Bob,
I checked the Windows location and there are many more profiles than I can see in QU
OK. let's get some detail:-
Can you see the Moab profiles in the Windows location?
Were you using an earlier version of QU before installing QU 2018, which version before and now?
Where in QU are you searching for printer profiles? It should be from the Printers and Settings tab.
When browsing for printer profiles, make sure the the Color Management window and the ICC Profile Selection window is set to printers, see screen shot attached.
If for some reason it is set to printers and the Moab profiles are not visible, then set to "All" and see if you can find them. It may be possibe they're somehow not designated as printer profiles.
If they're still not visible in QU, the only thing I can suggest is you go the to the Windows color folder and right click on the missing profiles to "Install Profile". Do that with one and check QU again.
Please report back that you checked all I suggested above and the results.
PS. Note that QU shows both the file name and description of a profile, they can be different so make sure you are checking in both columns.
