How to remove Russian audio tracks from .mkv files?

Hey, I’ve got this .mkv movie file that’s packed with three different Russian audio tracks. I want to strip those out and just keep things clean. What kind of software should I use for this? It's pretty weird, though—whenever I use VLC to check the available audio streams, it lists all three Russian tracks but doesn't even show an English option. Yet, I’m hearing English perfectly fine every single time. It plays the English track first, then jumps straight into the Russian ones. It’s like one of those poorly dubbed documentaries you see on network TV. Here’s a screenshot from my media player so you can see what I mean.

Just because you can hear English in the background doesn't mean the movie actually has an English audio track. What you're dealing with is just poor Russian dubbing where the original English dialogue bleeds through the mix. Your best bet is to just redownload the film and look for a version that has a proper English audio track.
