Some videos in my Apple TV library showing as songs and only playing audio

Im at the end of my rope with my TV app and watching my videos on my Apple TV. I have searched all the solutions, but none seem to directly address my issue. I could be wrong, but I haven't found it yet. My issue is that my Apple TV sees a number of the videos in my Library as Songs. Not all of them, but a pretty large number. Now, I have seen, the simple answer is no big deal. Go into your Music App, and classify them as Home Video or movies. However, when I go into my Music app on the desktop, those files do not appear. Anywhere. Not as songs, not as Music videos, not at all. But, when I do a search on my AppleTV, there they are! Classified as songs. If I try to play them, they just play audio, no video. So I search the TV app for the files and nope, not there either. However, when I Go into the folder that houses all of my videos, there they are! So I drag them into the TV app, and nothing. Nope. They do not show up. Now, until the latest OS upgrade, I have seen and watched these videos. They worked fine previously. And to add a little more mystery, when I use spotlight search for the titles, they WILL NOT show as files, but as images in the "app" results section. Someone please help! Sequoia 15.6.1 (24G90)
