Batch Create - plugin conflict causes incorrect password

I have just used Batch Create to create a dozen blogs and since it has the option to set passwords I chose to set my own passwords for them. The blogs get created I receive notification emails with MY passwords but I also get the notification email with auto-generated passwords and those work while my passwords don't work.

(I have to go in and manually change passwords for all blogs - which is not a pretty task at all)

Am I doing something incorrectly or is this a bug that requires fixing?
