That's strange. I should have started with these questions, I guess, but well, here we go: what platform do you play on? Is it PC, console? If PC, do you have the Steam, or GOG version? If Steam, you may try mods from the Worshop to fix those issues, there are some, that improve crafting, others, that unlock all vanilla recipes (but vanilla recipes should unlock with crafting at least one of the item). If you're on console version, there's probably no other help than sending support ticket with the issue described to Larian.
