How to display the accurate length of a playlist after software update?

Hi guys,

I just updated to the latest version of iTunes (iTunes 11, 163) and immediately noticed that the accurate, hours-and-minutes duration information about my playlists was missing. Instead, there's this vague "1.1 hours" (for example) line at the top of the screen.

Also, when I select a group of songs, there's no display of that group's duration like there used to be.

These may seem like small issues, but my work requires me to create playlists of very specific lengths, with different types of music represented for different periods of time. This change makes it basically impossible to use iTunes for my work anymore, which really *****.

Is there a fix for this? Or some sort of customer feedback avenue I'm presently unaware of?

And if not, is it possible to revert back to the previous version of iTunes?

Thank you for your time 🙂
