Subscriptions & Bulk Email

Test customer group - one test group member confirmed opt-in with # 1 of 5 possible subscriptions.

Test Email template configured with Subscription # 3.

Sent Bulk Merge email using Test template to Test group.

Even though test member is subscribed to only subcription # 1, they rec'd the bulk email.

Tested same Group with a Campaign Email configured to Subscription # 2.  Test member did not receive email (expected outcome).

So am I correct in that subscriptions work for Campaign Emails, but not Bulk Merge Emails?

Also, when I look at Bulk Merge Email in the Merge History, the Subcription that I had set is gone.  Several tests act the same - even though the email template is pre-configured with a subscription, and the same subscription is chosen for the Bulk Email, after the email is sent, the Subscription is gone after the email is sent.
