Syntax for coupling orders in version ≥ 3.2

Dear experts,

I'm using MadGraph 3.3.1 to generate the ttbar process at NLO, and decay it with MadSpin. Before MG 3.2, I would have written:

 generate p p > t t~ QED=0 QCD=2 [QCD]

In MG 3.3, if I do that, I get an error saying:

 "Potentially ambiguous 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".

So I rewrite it as:

 generate p p > t t~ aEW=0 aS=2 [QCD]

and now the generation succeeds. But to decay the tops, MadSpin needs to compute the matrix element for real emissions again, specifically:

 "generating the production square matrix element
 generate p p > t t~ aEW=0 aS=2 --no_warning=duplicate; define pert_QCD = -5 -4 -3 -2 -1 1 2 3 4 5 21; add process p p > t t~ pert_QCD aEW=0 aS=2 --no_warning=duplicate"

and this fails here on the pert_QCD part (which is just adding another parton) because it's not covered by aS=2 and therefore "there is no diagram". I suspect that here MadSpin should really have considered QCD=3 but couldn't translate it from aS=2.

At that point, I can trick it into finding diagrams with QCD=3 by requesting it from the start (in this particular case, it doesn't change the diagrams that are generated in MadGraph):

 generate p p > t t~ aEW=0 aS=3 [QCD]

and now MadSpin is happy with the diagrams but still complains as "Decay processes cannot specify squared orders constraints" - and aS/aEW are constraints on QCD^2/QED^2 (?)

So what's the proper way of writing the generation + decay processes? Is this fixed in newer versions of MG?

Cheers,
Baptiste
