You seem to have 2 active gigs with the same title and description - but one in a different category to the other. Surely you might get in trouble for that.
You could create a video for your gig that contains the training (you could also put text in the video to help stop it being resold or uploaded anywhere). Maybe a document too. You could also answer questions if wanted as text on the order page.
You could also ask CS if you can create a training thing on some site for the gig (and put info about it on the gig description). Or maybe you could deliver software that had the training (though buyers might see that as a risk?). A video/document/.PDF might be better, or with permission from CS the training thing on a website.
