Enable builder on no pages bugged?

Hello,
thank you for this plugin. I try to use it in latest version, with only global settings. That means I do not want to have the builder injected into any editor.

But when I visit General Options and try to delete all available types and save the configuration, after reloading page a new item called Array appears and the editor is then injected into every editor page. I think this is a bug. I’d appreciate to be able to save a configuration, in which the builder will not be injected anywhere.

Thank you for your work and support.
