Missing songs from CD after syncing Apple Music on Windows to iPhone

I downloaded a music cd into the apple music app on my windows laptop. I can see the entire cd in that app, but when I tried to put it on my phone, only the second half of the cd is now on the phone. I have tried syncing it several times but am still missing the first four songs on my phone. how can I get those missing songs from the apple music app onto my iphone?
