Service requests are not assigned to queue on next Gen Helpdesk

Summary:

Hi , we are working on migrating Classic HR Helpdesk to Nextgen Redwood helpdesk.

After completing migration jobs , i can see all queues has been migrated and i have manually created the queue assignment rules based on categories.

I have validated queue assignment profile option and run the schedule process as well , however queue is not automatically assigning and remaining blank.

Note: i have disable the omnichannel as we need to assign queues based on categories.

Please review screenshot below and let me know if i am missing any steps?
