Layer slow to load

So, here's what I see. I looked just at slide 1.4. If you have similar problems on the others, it may be related to these issues. I attached a modified version of your project for reference.

For Layer 1 (FS Results):

1. On the Base Layer, you have several state change triggers associated with the timeline start that overlap with others later on linked to the calculate button click. Since you don't need to set the states of layer objects when the base layer timeline starts, these are likely uneeded. I disabled them. 
2. Related to changing the states of objects on the other layers from the base layer, it seems that changing an object's state is causing it to immediately start its timeline. It also happens if done on the on the layer itself: Changing the state of an object before it reaches its timeline entry is causing it to appear and start its timeline early. This is not noticable if the object starts at 0 seconds, but for things starting later in the timeline, it is messing up the timings.
3. This does not seem like it would be the expected behavior and may be a bug that should be submitted to Articulate support for evaluation.
4. The workaround for your situation, since your Combined score - results rectangle is delayed on its layer and requires a state change, is to 
   1. Create a cue point (right click on the top of the timeline) on the layer's timeline where the rectangle should begin (I put it at 1.5 seconds).
   2. Copy the 3 Set state of Combine score - results to... triggers from the Base Layer to the FS Results Layer 
   3. Disable the original 3 triggers on the Base Layer.
   4. Set the new FS Results Layer triggers to start when timeline reaches cue poit #1 (1.5sec, or wherever).
5. Now, the HUA Overall text will appear first, then the results rectangle will start its animation and state change 0.5 seconds later.

For Layer 2:

1. You have the Show layer Combined Good Layer trigger set to fire AFTER the FS Results Layer ends.
2. Change that to something sooner, like maybe to the same cue point you set above. That way the animations will flow together without the delays.

As a side note: You may want to set your timeline objects to Show Until End (right click on blocks in the timeline) to make sure ethey don't disappear as soon as the timeline runs out, unless that's what you want. I'm not sure what's keeping your objects visible right now, but when I was tesing, my edits caused them to start vanishing when the timeline ended, which would be normal if they're not set to persist.
