I wish you had mentioned you needed to use the keyboard buttons to get it to display that extra bit, I was wondering what i was missing.
Groove settings leave a lot to be desired: http://www.howtogeek.com/225046/how-to-add-and-organize-music-on-windows-10-using-the-groove-music-app/
Groove is a nuisance, I mistakenly ran it a few weeks ago and now every day it runs runtime broker and eats 20% CPU for about 20 minutes every few hours unless I change a setting every day.
I am hoping the anniversary update to windows adds new features to Groove but then I live in hope they make multiple desktops useful too. So we shall see.
