Having issues mass producing cards from Youtube video

[Manny]

What I am running: Linux (ElementaryOS)
What version of Migaku: Not sure how to check but whatever the latest version is I believe
What version of Anki: 2.1.49
Feature: mass-producing cards for Spanish

I attempted to mass-produce about 93 cards the other day. I had to go through a few hoops to do so, including eliminating all of the verb forms that are marked as unknown despite the base word being known, and eventually I let the thing roll. I come back to try out the flashcards and the audio is completely messed up. I put it on "mute" mode while producing them but I am not sure if that made a difference or where the issue stems from. It plays a tiny tiny clip of sometimes completely unrelated audio when I use the card.
Here is a link with an example from my iPhone: https://drive.google.com/file/d/1zQUQdEOHLjSP9XAAevK7ZA2X7TWTmpUf/view?usp=sharing
The first and last card were mass-produced, the others I did individually.
