Adding index cards by doubleclicking, cards autopopulate?

I’ve got a weird problem. When I double click in a folder to add a new index card, the card contains text. Sometimes it’s from one of my character sheets, sometimes it’s data from the snowflake template I’m using.

As long as I right click and add new text, the index card is blank, the way it should be.

Oh, to clarify, sometimes the text is in the index card view, but it also adds text inside the card, which should be a scene…

Anybody know why it would do this?
