Denying ticket does not move it to "Denied" stage in pipeline.

I created a Kanban board as my pipeline for new ticket request that come in when requestors need help with something. They rest of the automation works well, however for some reason I when opening a ticket and denying it, it does not move to the "Denied" stage in the pipeline, but rather it stays in the "Requests Received" stage. I would appreciate assistance resolving this. Thank you.
