Comment 2 for bug 2011588

I think I cannot use this notation DMV<=2 [QCD] in this version of madgraph I get this error:

Command "generate p p > t t~ y1 DMV<=2 [QCD]" interrupted with error:
Exception : Potentially ambigious syntax detected. Note that the syntax of paper 1804.10017 (used in 3.0.x) is not used anymore (since version 3.1.0).
 If you want to follow the syntax of that paper, you can just replace "QED" by "aEW" and "QCD" by "aS".
 More information here: http://amcatnlo.cern.ch/co.htm
 If you know the current meaning of the syntax you can bypass this crash by running (once per machine) this command:
  set acknowledged_v3.1_syntax True --global
