@JeEnYuS504 I just tested this on multiple offline dynasties and it looks like it is working as intended. If you were able to edit these before, then that sounds like the bug and they now fixed it.
In my opinion, you should not be able to change your coaches pipeline because it represents where they grew up and the relatinships they have with that region of people. Those don't just change when you get a new job.
This is why we have school based pipelines as well to ensure that school's have an identity as well as the individual coaches.
I would encourage you to look in the next offseason and try to find more assistants with pipelines that match what you are looking for.
