UPDATE: Problem still exists, for me, if the plug-in is enabled when people register they do not appear onsite as having registered. Also, when going to ACP to Approve their registration, they are already (automatically) approved. With the plugin disabled, everything works as expected: people register, I get an email notification to sign in to ACP and Approve their registration, I do this and all is well. If I enable the plugin, I'm back to the situation I describe. Sorry you are not able to demonstrate this behavior so I understand you will not be able to fix it. I liked what the plugin did before when it was working properly for me, but now my only recourse is to disable it and stop using it.
