Error: The file is not displayed in the text editor because it is a directory.

Some note types can't be open and I've got this error "The file is not displayed in the text editor because it is a directory."

I think the problem is with card's templates that are ending with "?" sign

The icons next to Front and Back are different.

I've tested this and it does indeed seem to be a problem with the "?" in the name of a card templates.
I'll see if I can fix it.

Interestingly, this problem doesn't occur when you open the note types as a workspace folder using the button in the top right corner of the anki-editor column. So you could use that as a workaround for now.

This has been fixed and published in version 1.0.4 .
