Removing Podcast listing from Sync Settings list

Mac Mini M2 (2023)

Sonoma 15.1.1

Music v 1.5.1.24

I am trying to remove several podcasts (see attachment) from my Sync Settings without success. I have flushed old podcast listings from my Library > Group Containers and Preferences without success. I am not subscribed to any of these podcasts. I have run searches on my Mac looking for the podcast names and found nothing. I have also reset my iPod Classic twice but the listings remain.

Any other thoughts?

TIA
