you may be on to something there, I didn't think about it from that point of view. I think it cleared up for me somewhere between 25-30.. But I thought it was a UI bug after the patch on my rogue.. I was using the same layout..
What I did to get around it was after I mazzified. I would stealth and add both sets of buttons I needed for a while. The other thing you could do is put them in the context menu, but if you mazzify they would go away. I downloaded another program called lunar sphere and used it for a while for exactly that problem.. I had basically a second set of buttons on another program.

Hope that helps hold you over.
