iOS 18 Music App Genre Issue

Hi there folks. I have a question that I am hoping to get an answer to or at least some insight on. The issue I am having involves an iPhone 16 Pro running iOS 18.3 where the music app does not show all of the songs located in a specific genre. For example, I have a rock genre on my MacBook and all of the songs located within that genre show up just fine however when the music is synced to my phone only a very small handful of songs show up in that genre. It is also not just the rock genre having this issue, essentially every genre on my phone has songs missing within them. This issue has been ongoing since day one back in September with the initial release of iOS 18. I have tried pretty much everything at this point to fix this, I have tried completely resetting and reinstalling my music on my Mac as well as deleting all of the music from my phone and re-syncing but nothing seems to work. What are your guys’ thoughts on this and is anyone else experiencing the same?

Thank you in advance for the help!
