Hi Kaitlyn
Good news! I was able to figure out what the issue is.
It looks like when you are applying the rules you are applying them to the parent item of the grouped shape (the combination of the two shapes that make up each section of the dashboard). You can accomplish this by clicking once on the grouped shape and then applying the rule. This will apply the icon to all components of the group.
To apply the icon to just one component of the group you will need to first un-apply it from the grouped shape as a whole and then apply it to just the outer shape. You will have to double-click on the outer shape to access the conditional formatting settings of just that shape.
I have done this with the top left shape in your dummy dashboard. Please let me know if you have any further questions or concerns!
