Hi Ethan,
We attempted setting the Client Cache to null and it is not possible to set it to null. Also thank you for the clarification on the ServerCache.
I completed a test project to show the issue with GenerateCacheImages. I created a sample Shapefile that matched the project of our clients shapefiles. Here are some images below showing the issue.
When the ServerCache is built by GenerateCacheImages:

When the ServerCache is built on the fly without GenerateCacheImages:
