Last 24 Hours shows nothing for the last 22 hrs

So for the past few weeks, I've been noticing that my 24 hrs Bandwith chart is missing alot of the previous hours.

Here is today's screenshot of the last 24hrs. (today I used 29GB in downloads, but this only shows 6GB)

This chart should show more data, because wife & kids were home today, and there was alot of video streaming going on.

I also have it setup to Backup every hour to CIFS1
