Skin Animal skill not unlocking after reading blueprint

[TronBronson]

Describe the bug
I used the books to create the "Skin Animal Research" blueprint which the wiki thing says teaches me to skin animals and i cannot skin animals nor does the blueprint indicate "already read". Reading it multiple times doesn't work. I see there is another option through creating a clay tablet with the research bench but the "Skin Animal Tablet" isn't anywhere in the build menu even though it says it doesn't require a book. So now i'm stuck not being able to skin the rabbits i breed

Expected behavior
I thought i would be able to skin rabbits after reading the blue print "skin animals". I also expected to be able to create the alternative option, which doesn't require a book, but even with all of the materials there is no recipe for the tablet in the build menu, just the blueprint.

UPDATE: I am blind and didn't know it is now "butcher carcass" and is unlocked from the beginning. I made the blueprint, clicked the rabbit and didn't see "skin" so I moved on toward making the tablet. You don't need them.
