Category RSS when Feedburner Gets in the Way

Hi there –

I know that you should be able to pull an RSS feed on a certain category simply by doing this:

https://www.example.com/?cat=42&feed=rss2

In my case, feedburner seems to get in the way, and no matter what category I chose, it gets redirected to the main RSS feed.

For example:
https://www.triplepundit.com/?cat=42&feed=rss2

Anyone know a way to get around this?

Thanks!
