Google Analytics Report using bad URL’s

I am running Google Analytics using the Google Analytics plugin for WP. It works great. Stats come in every day. However, there is one glitch I’d like to fix (or see fixed).

The URL’s which show up in my analytics report have an extra bit, superfluous, which breaks the link. The links in question are located in the full report for Content Overview. Here is an example:

https://soundunreason.com/InkWell/Welcome.html?p=497

The URL should read:

https://soundunreason.com/InkWell/?p=497

I don’t understand why they are being listed as such in the reports. Clearly no one is visiting pages by the first link (it will never work). The pages visited are all like the second link.

Anybody got a clue?
