Hope you can help

Welp, that's a bit of an oversight on my part, that's been there a while. I actually found 2 more bugs in the config while fixing this one, one old one and one thing that I should have changed as part of upgrading to Python 3. Guess I haven't changed my own settings in ages.

Out of curiosity (I don't have a Calibre 4.x install on my system), does 1.2.x not work on older Calibre versions or did you just choose to stick with an older version of the plugin? I'd expect it to work but I haven't tested it.
