Delete synced media from an iPad-pro?

Hi:

I just completed syncing an entire Music library to an iPad and now I wish to delete some but not all of the entries from the iPad but not the server. I can’t seem to find anyplace to delete an artist, album, or track(s).

I have no option to delete when viewing an individual item.

When I view the sync results I have a message stating “not all items were synced” & when I click on the message to get a list of what was not synced nothing is listed and my only option is to delete the entire library.

I am using IOS 4.2.1. Anyone have any ideas?
