Since you're new to both banking and credit analysis, I would suggest a nice chat with your supervisor (assuming that's the person who told you to only spread the first page). Be friendly, not confrontational. Just ask why there is a difference in the training you had versus the bank's practice, since the two are so different.
I don't know why they would bother with the training on the software if they don't use it the way it was intended. (I'm not familiar with that software.)
