How to remove email address from Selzy

Good evening, Im attempting to have Pabbly connect remove an email address when a specific Pipeline opportunity is reached.  The first two steps in the workflow work (pipeline in Moxie, filter in Pabbly) seem to work however even though the response result is empty and the it shows the following note:  "Important Note: You'll get empty response if the subscriber contact is unsubscribed from the list."  the subscriber is still listed in my Selzy contacts
