I set up my Voice settings on one of my queues to use an In-Queue Call flow that allows a callback request. Placed a call into a different queue, answered it, did a blind transfer to the other queue (by typing the name, selecting it in the Blind Transfer dialog and transferring). On the calling phone, I heard the prompts to receive a callback, chose that option, and the callback was properly created in the queue the call was transferred to.
So, I am unable to reproduce what you describe, Angie.
Have you tried putting a Play Audio action in to play back the Call.CurrentQueue.Name value within the IN-Queue flow just before the Callback action, to make sure it has the right queue?
