The currencies tab is full of checkboxes but only a few on the very bottom of the list show an icon or text to signify what it is. I've tried clearing all settings for the add-on and removing and reinstalling. I also inquired on the Discord channel.

that's very strange. normally it should gather that data again on re-open. it sometimes has issues getting the data a first time from the server so returns blank.

I'll look into it this week.

This is fixed with the latest release.
