Hello, I hope you're doing well.

I've recently begun learning how to make simplistic data packs, by using the datapack you provided in a previous issue regarding Hyenas not accepting rotten flesh.
Using that as an example on how to make datapacks, so that I can specify different items of choice for various animals and alter their stats, I tried to change some health values for bears to make them bulkier.
In the process of this, I noticed that Rhinos and Bison are bred with melon slices and wheat, respectively, by looking into the json files of the entities folder.

Weirdly enough... I can't actually breed then with these items.
I've even tried to make datapack for the rhinos and bisons, to 'force' them to use the favorite items as breeding triggers. (Again, using your Hyena fix datapack as example).
I've set the config files in a way so that only a player can trigger the breeding of two animals, if you use their favorite item, and they're male+female.
Every other animal seems to heed the config and datapack changes.
Except the Rhino (any variation) and the Bison (any variation).

Do you know about this?
Can you reproduce this on your end?
I have no mods installed that /Theoretically/ could mess with these mechanics.
And since I made the pack myself, I've been very careful not to use mods or turn on configs for mods that could potentially mes with other mods.

Let me know what you think of this bug.
