Layer slow to load

Hi. I'm working on my first Storyline project.

In a previous discussion about slide layer "lag" a community member responded:

I would check two things

• if there is an animation for the entrance of the layer
• does the timeline for the layer begin at the start

I have several slides that load two different layers with results based on user input. The first layer that appears just has simple shapes with some text and variables in them. The second results layers that appear include three small graphics (totaling about 45KB) that animate in one at a time while an mp3 (under 10KB) plays. There's a long delay before the second results layers appear which might make users think they're done with the slide before they really are. How can I speed up the loading of the results layers? Don't they get preloaded with the slide? What should I be looking for that might cause a delay? If having an animation at the entrance of a layer causes a delay, how can I ameliorate that?

I've included a video demonstrating the issue. Thank you for any insight you can provide.

P.S. You'll also notice that on the first results layer that appears, the text "Housing Unit Assessment Overall" shows up after the rectangles. It's supposed to show up before the "Good!" rectangle to its right, but no matter where I try to time its entrance on the timeline (by having it show up later in the timeline than the appearance of the "Good!" rectangle), it shows up after. Any insight into how to troubleshoot that would also be helpful.
