Monaural broadcast FM is much less sensitive to both multi-path effects, 
and low-level on-channel RFI that stereo.  You're in a building
  presumably with at least some kind of not-entirely-rf-permeable skin, 
and likely lots of other electronic equipment producing RF noise.
 That's not ideal for a radio receiver.
