Transmutation Tablet not functioning correctly

Title: Transmutation Tablet not functioning correctly

Version: 3.1.2

OS: Windows 7 Home premium 64-bit

Java Version: 7

Description of Problem:

I do a lot of pixel art on my server (Nature'S Revenge). Since I do not have admin/access to creative, I've been using a Transmutation Tablet to make the various colors of wool and wood and other materials I would need to make my next piece.

2 days ago, I logged in and my tablet was not functioning correctly. The usual routine would be placing a piece of wool in the target slot to help reset the "blank circle" bug, but it doesn't change. The entire output circle remains the same. Taking 1 or a stack will leave a blank slot there until you exit and return to the tablet (depending on how much EMC is availabe).

I'm not entirely sure what needs to be done as I'm not an admin (though am friends with said admins but prefer to play without access to creative). I'm hoping to come across a solution that doesn't involve deleting any data but will have to if it boils down to it.
