Code dump in Bandwidth and Web usagle data

[DullRazr]

I've been downloading the Bandwidth usage and Web usage data from my gargoyle router on a daily basis for a couple of months now. All of the sudden (within the last week) both files seem to have some sort of code dump appended to the data. A few sample lines of the code are below (tried to attach the files, but the site would not accept .txt, .csv, .prn or .docx files)
Any Idea what this is? Any Idea how to get rid of it?

Gargoyle Version: 1.6.2
Model:D-Link DIR-835 rev. A1
Device Configuration: Gateway

I need a copy of the file to inspect as well as what browser you were using at the time.

Please use any free file host and link it to here. E.g. Dropbox
