So, I created a simple information box lower third in AE. It slides in from the left (using position keyframes), the text fades in once the boxes reach their position (uses opacity keyframes on text). After displaying for about 12 seconds, the entire graphic is springs up and then off screen. At least, that is how I made it in AE. I exported it as a MOGRT (using essential graphics) and added it to a composition in Pr. Instead of the smooth slide in from the left, it just pops into place. Instead of the entire graphic springing up and then off screen, only the text springs up and disappears. I am not sure what's going on because when I play it in AE, everything works perfectly.
