Obsidian to Anki custom regex puts everything into 1 field despite multiple groups

Things I have tried

Making a note with the same notetype but with the usual format (fieldname: contents) - Works
Enabling auto file link in a certain field - Works

What I’m trying to do

I dislike the format required to convert obsidian notes into anki. I want to make it so the notes are in a pleasant format while being able to import them into Anki as flashcards.
I have tried the following regex regex101: build, test, and debug regex which seems to work on the website, but the plugin just puts everything into one field.
