Sabertooth Control Missing?

I have a Sabertooth 2x10, that I used in the past with a Hbridge control, however after updating to the most current versions of firmware and ARC, I no longer see this control as a choice as I did before, based on a post I had found previously:

------------------Forum Post------------- 2. Select "Add Controls" on the Ribbon bar 3. Select the "HBridges" Button 4. Select the "Sabertooth Serial Movement Panel" 5. Select the Gear Icon (Settings) on the Movement Panel and select your Serial Port pin from the drop down menu, corresponding to whichever Digital pin you hooked your Sabertooth too.

Now I just see two items in the pull down down for the Hbridge control:

4 Wire HBridge Movement Panel and BV4113 Movement Panel.

What am I missing?
