When creating a category queue, you have the option to choose "Enable Future Post Queuing" to automatically queue any new posts created in the selected category (add new posts to a category queue to be reused, when tagged with that queue's category). But unfortunately, this also applies to posts that are already queued. Meaning that once a queued post is added to the schedule from the queue/published, it gets added BACK into the queue, creating a duplicate post. This feature should ONLY apply to NEW posts added into the queue, not existing posts in the queue which get posted again.
This is very frustrating not only because it inflates the actual number of posts that are in a category queue, but if you ever want to edit one of those posts, first of all, you have to delete and recreate the queue entirely, and second, you have to make edits to the post and then manually delete all of the duplicate posts. It's tedious and time-consuming, especially for bigger queues. The system should be able to recognize posts that are being reused. They should not be created as separate, duplicate posts.
When the system pulls a post to be reused, it should effectively "link" to the existing post in the queue, not create a new one that is separate with no way for the system to understand that they are the same exact post.
I am unsure if this is a bug or an intentional function.
