Preview not the same as export- Animate

[Broderick5EBF]

Hey everyone, I am new to animate so I apologize in advance for my lack of knowledge. 

I've been working on this infographic animation for about a week now and I once exporting it, it doesn't look like the playhead. After editing, I will export to get a better sense of the animation, avoiding the sluggish previews, and it doesn't show some of the edits. I did a motion guide to several items and the exported video does not show their movements, like the playhead shows. Rather the images just stay in place, unmoving and unchanging. I've attached a video showing the problem, (at 32 second) when the "windows" are guided on a motion guide to go in a circle animation and fly downward, as shown in the playhead here. Any idea what's wrong with my export or settings?

I ended up converting it to frame-by-frame animation, and that worked. Still would be nice to know if someone had another answer.
