Action bar & cooking recipe book glitch

I’ve had this ongoing error on my action bars, particularly regarding things like buff items.

On my Warlock I have the healthstone on my action bar so I can click on it as needed. However, when I run out and renew my healthstones in my bag, it does not show up as available on the action bar. I have to go in, delete it and then replace it again. This happens constantly.

Also, if I go to the cook to buy materials for dishes, they will not show up on the recipe as being available. I have to close the book and then open it again for the material to appear.
