Trying to render 2 separate formats - doesn't work anymore

In AME CC2017, I used to be able to render out two different formats, a Quicktime and an MPEG2 file, simultaneously.  I would set up the first render in Premiere and Queue it, then Duplicate the render in AME under the same Premiere sequence and change the AME preset to my second format.  Now, in CC2018, that's not working, and AME show up as Not Responding, then crashes.  I like to do multiple renders this way because AME would render both files at the same time and it seemed to be quicker, as opposed to rendering one at a time.  I can still set up multiple renders, but I have to switch back to Premiere Pro for each render.

Is there something that I'm doing wrong, or is this another bug?
