When configuring the settings for readable passphrase, the text labels for the fake words checkbox are misleading. See below:

By labeling this part "Exclude," I would assume that checking this box would not include fake words in the passphrase generation. Instead, the opposite happens. The tooltip alludes to this; however, it should be more obvious at first glance.

I propose changing this label to say "Include" instead of "Exclude" for clarity, as seen below. I would be more than happy to make this change myself in a pull request.
