Empty folders on Marantz SR6007

[demonachizer]

I have connected to Spotify with a Marantz SR6007 receiver and am noticing a HUGE number of empty folders.  It is to the point of being unuseable for certain searches.  Steps to reproduce:

Search>Gould

Search Artist

Select Glenn Gould

Results show 490 Albums (Should be more around 100)

When I go into most of them it says ---Empty---

Is there a way to filter empty results out?  Is this normal expected behavior?  If any of you have the same receiver could you do a test search following the steps above and let me know if the results are similar?
