I too had this same problem. What I did was I deleted all my game add-ons (Dawguard, Dragonborn and Heartfire) and when I purchased the Alchemy Labratory from the Steward again, it fixed the problem for me. After purchasing the Labratory, you should be able to re-download the game add-ons and still be able to use your Alchemy Labratory. Hope this helped.
