Question / Help Remuxed MKV files show no duration

Hey there people!

So I was remuxing some files, it claimed that the file I was trying to remuxing was an MP4 file, but it wasn't. It was an MKV file with a duration, proper file size, totally normal. I went to remux it to an ACTUAL MP4, and when I did, it remuxed instantly, and outputted an MP4 file with no duration and a few KB of data.

What happened? Is it possible to recover these files, or am I out of luck because they're technically overwritten? Never had this issue before. Thanks!
