Album Art oddness

Hi,

For some reason in my Browse listing of albums the correct album art is showing, but in the Playback and Queue tabs some random image appears.

E.g the image link locations for one album are showing as (with http:// on the front):

192.168.0.60/albumart?web=U2/Rattle%20And%20Hum/large&icon=fa-dot-circle-o
192.168.0.60/albumart?web=U2/Rattle%20And%20Hum/large&path=%2Fmnt%2FNAS%2FMedia%2FMusic

with the top link displaying the correct image.

Any ideas how to fix this?
