no Doctor Scott presentations after episode?

I was watching Dinosaur Train, and the one thing I've noticed that when the 2nd episode ended, Dr. Scott's educational presentation wasn't shown. Instead they just played a Dinosaur Train music video like Don's collecting song.  Usually Dr. Scott's presentation was shown after both episodes. Funny that I have a Dinosaur Train DVD with 5 episodes and there was no presentation of Dr. Scott at all.
