Getting Dorico to distinguish ensembles a3, a6, a8

The Vienna VSL SE Library for Brass contains samples called “Trumpet-ens 3” and “Trumpet-ens 6”, Horn-ens 4, Horn-ens 8, etc.

In Dorico, I create a new score, define two section players (one in C and the other in Bb), load the “Trumpet-ens 3” VST into the first and load “Trumpet-ens 6” into the second.

I assign their EM (e.g. Studio SE - Trumpets) and save the end-points as “Studio SE - Trumpet-ens 3” and “Studio SE - Trumpet-ens 6”, respectively. Everything plays back as expected.

With the score still open, I create a new playback template (called “test”) into which I load only these two created endpoints created above, and save; I then apply and close the template.

Dorico assigns exactly the same definition to both : “Trumpet-ens 3”. Ens- 6 is nowhere in sight.

Why is that?

Same problem with section players for flutes, clarinets, horns, trombones, etc.

I have a similar setup with Eastwest ensemble patches and the endpoints work for me. I don’t actually show them in my print layout, though. One thing I did was to change the instrument names (Setup → Edit Names) to “Flutes a3”, “Trumpets a2” etc. Perhaps that plays a role? Otherwise, how would Dorico be able to distinguish between the different section players?
