Additional channels not working on Musio

[Rodriam69]

Hello!
I created a template for using Cinesamples Musio on Reaper. It worked very well when I was creating it, it took me about 2 weeks to finish it and the articulations were mapped to each channel correctly. But now, a month later, I am starting a new project, loaded the template and this happens for example on the violins 1 patch, with 4 instances: on midi channel 1 all articulations changes work OK, but when changing to the ones on channel 2, 3 or 4 it stucks in only one of them, clicking the buttons sends MIDI data to the corresponding channel but do not change the keyswitch. Only way was to delete the articulations and adding them again, not the best solution each time I will use a new instrument with several channels. Can you tell me what can I do? Thank you!

EDIT: I found that when I click on the articulations it does send midi data, but only for one articulation. If I click on the other ones nothing happens, just when I click the one where it stucks.
