MacIII rogue prism in beam in Aug3d

Question

Hello... 
 I have a show with some MacIIIs, which we are transferring from MA to Eos, with the first stage of that transfer an MA import by ETC. 
 I've added position information to the rig for Aug3D. 
 It seems to be showing the MacIIIs with a prism (which I think is the 'BeamFX' parameter) permanently in the beam. I can rotate it, but I can't get rid of it. 
 Fixture is showing the '3D' tag in the patch. 
 DMX output is showing 0 on the BeamFX channel, which the MacIII manual says should be no prism. 
 I can't get to the real lights until next week, so (as is often the case with virtual lighting) am left wondering which is correct.... But altering the BeamFX parameter seems to have no effect on Aug3D, so I'm thinking Aug3D might be wrong. 
 Any thoughts or known issues, I'd love to hear them? 
 Thanks, 
 Rob.

In your custom fixture profile the respective range of the prism parameter doesn't seem to be labelled in a way that makes A3d understand what it does. You can send me the showfile so I can have a look if I can fix that, otherwise you will have to move over to the official and current fixture profile for a Mac III which after a quick test doesn't exhibit the problem.
