Can not Craft some items within the new snapshot

It will not allow me to craft a horse saddle or horse armor. When I put the correct ingredients in and in the correct shape then it should give me an option to craft the item I am trying to craft. Yet when doing this for horse armor and saddle, it does not allow me.

I do find it weird because it allows me to craft carpets and leads and other items from these snapshots, but not these.

Help would be appreciated.
Thank you.
