Saving "Bulk-subscribe all unsubscribed users" does the opposite

Problem/Motivation

Hi all,

In the plugin config, checking and saving "Bulk-subscribe all unsubscribed users" does not save unsubscribed users with the default settings. In my testing, it actually de-selected the content type subscribed users had chosen leading to some confusion. Subscribed users Master settings/Detailed settings were left untouched.

The description beneath the "Bulk-subscribe all unsubscribed users" checkbox is as follows:
'Apply “Default Settings” to all non-blocked users that do not already subscribe to notifications. Users that already has enabled “Receive email notifications” under their “Notify Settings” will not be affected. '

The “Default Settings” are correct, and I have tested they work. When a new user is created that have the default settings.

Does any one else experience this?

Cheers
