This is the page in question:
https://en.wikipedia.org/w/index.php?title=Education_Program:Consumer_Reports/Wikipedia_Volunteer_Corps_Course_(winter_2015)&action=history
The third edit to the page was vandalism by an IP address. However, the page history shows the IP address of the person/account reading the page and not the IP that made the edit. The IP that apparently made the edit has zero contributions: https://en.wikipedia.org/wiki/Special:Contributions/72.68.239.80
Edit The IP's contributions are showing up now in Special:Contributions at least, but the bug still lives.
I think this is a problem.
