Local Files in Playlist Not Showing Up on Iphone Although Synced

[d-g]

Have Mac Desktop App and IOS. I'm trying to be able to play two local songs from my playlist on my iphone, however, they do not show up in the playlist. On my iphone, the playlist says the correct number of songs (19), but the local file songs are missing those two local files (so only 17 are shown).

I have them downloaded offline on both my mac and iphone. If I change the order of the playlist on my iphone, then the order changes automatically on my desktop, so I know the two are synced properly.

I also have the two files synced to Itunes and the Music app.

They are also both mp3 files.

Edit: They aren't protected by DRM, I checked.

Any thoughts or solutions?
