Description of your issue, suggested solution and other information

Hi,
I'm trying to download a video from Facebook, and when using Youtube-dl, another video is being downloaded, instead of the video that I was watching online.
The video's url is:
https://www.facebook.com/23tv.tv/videos/1234088389965246/

Here are some photos that demonstrate the result:
When I watch the video online, I get this video:

And when downloading the video (using to most updated Youtube-dl version), I get this video:

I'll add that this is the first time I've encountered something like that. Usually Youtube-dl works perfectly, and I get the same video both when watching online and when downloading it using Youtube-dl.

Any help would be appreciated. Thanks!!
