The two are measured at different places and the "Total" is the ground truth. It is measured at the socket level and counts all of the bytes in/out as they are transmitted/read. The content-type breakdown takes the sized for each decoded request and adds them up but it will be missing anything it can't identify (bug), TLS certificates/overhead and possibly a few other things that don't come to mind.
