Pressing ENTER shouldn't add a new flash card

Right now I want to add a long answer to a flashcard. I want to format it nicely, so it doesn’t look like a mess. But each time I press ENTER, it makes a new flashcard. This is terrible.

The only way to increase the flashcard size, for lack of better term, is to use SHIFT+ENTER. I then have to copy all the text in there, without having any separate lines, and then format it in Remnote, which is a terrible and finicky system.
