Restored my iphone 5s now my itunes library won't sync no matter what I do. What can I do to get my music back on my iphone?

I did a complete delete & restore on my iphone 5s . Icloud restored all my settings. When I went to sync from itunes, (all songs & videos are checked, as well as the "sync only checked music & videos") it acts like thre's no music to sync & just finishes up. Itunes is up to date: 11.1.3.8.

Box for maually managing music & videos only says "Manually manage videos".

After I connect my iphone via lightning wire & click on the "iphone" tab on the right side, then I click on the "music" tab, all I see is a check box telling mme that I can sync my voice memos. Nothing else. SOMETHING is wrong!!!!

I've restarted everything, my pc, (windows 7, constantly updated), my iphone 5s several times, but nothihng doing.

PLEASE HELP!!
