I am able to set a default queue topic duration to empty if I don't put a value in it. However, once a default duration is established, I am unable to set it back to empty. The value becomes zero.
I am able to perform this for the project in the queue details screen, just not in the queue topic.
I have approximately 23 queue topics which I want the default duration to be empty, so I'll have to recreate 23 queue topics. If a system admin adds ANY value to my default duration to a queue topic, then I'll be forced to rewrite the queue topic again.
