Volusion Store Stats vs. Cloudflare Analytics

I have a Volusion store and we’ve got Cloudflare setup as the CDN, however, my last bandwidth bill from Volusion was huge and it was mostly images which has me kind of confused, shouldn’t those be going through Cloudlfare?

So I was looking at the Volusion Stats and the Cloudflare stats and trying to compare them. Cloudflare shows 12.78 GB total bandwidth from 7/8-8/8 while Volusion shows 28.06 GB total. Is Cloudflare just showing what went through Cloudflare?

Also is there any way to see custom date ranges in the analytics? I really need to see what happened between 6/20-7/19 when my huge Volusion bill was.
