As Steven said, that's how you have it configured from library tabs. So if you want to change it, adjust the setting in another library tab, not in now playing tab.
Thank you so much, will have a fiddle tomorrow
Never did manage to locate that elusive LIBRARY TAB of which you spoke, however I DID find an option to change the PLAYING TRACKS LIST LAYOUT in COMPACT PLAYER LAYOUT.
by:
(right click on the header bar to add fields or drag column header to rearrange or resize the columns).
This didn't resolve my original query, but Compact Mode looks pretty close to how I intended the Now Playing, Artist View to look!

(Any sign of a release of MB 3.2 anytime soon please??)
