sync music library option missing
I am having issues syncing my music library to my iphone while I have it plugged into my laptop. I have Windows, Iphone XR. My iphone is showing up when I plug it in and Itunes is running. It will back up, it updates my icloud music library, even adding doubles. My issue is, not all of my music was added when I first synced my phone. When I first got the phone and set it up with Itunes, and I clicked on the phone icon, then went to music, it gave me the option to sync entire library and voice memo's. Now it's only showing me voice memo option. The songs show up on my phone but they have a cloud with a "!" in the middle. In my itunes library, some songs say "waiting", "matched", "apple music". Some have a cloud with a down arrow inside, others have a dotted cloud. HELP!!! I have attached a picture of what itunes shows me when I go to sync my music in itunes.
iPhone XR, iOS 13
