Needing Help Updating a Resource Pack Please!

Hi all,

I am updating a resource pack for a server from 1.21.3 -> 1.21.11. This server is Equestrian themed, and we had custom saddle & leather horse armor models. However I think the path for the textures was changed in an update? I just cant find anything about it online & I'm loosing years off my life lol!

The issue I'm having is the saddle & leather armor texture is not showing up. For context, we are using Fresh Animations as well, & I have updated Fresh Animations to 1.21.11.
We have a custom saddle that looks more realistic & the leather horse armor looks like a saddle pad. For context, the first photo is how it's looking now, and the second photo is what it should look like. Iron, gold, and diamond armor have their own custom models that seemingly haven't been affected.
I have a separate horse_saddle.png in textures/entity/horse/ & a horse_armor_leather.png in entity/horse/armor. I also have both in entity/equipment/horse_body. I'm just not sure what I'm missing!

Although its not the end of the world, it was a nice feature to have on an equestrian themed server. So if anyone has any ideas on how I can remedy this it would be appreciated, thank you!
