Hi @Sean_Moran and thank you for reaching out!
Apologies for the inconvenience this is causing you. Please have a look at the post my colleague @Marie wrote a few weeks ago: Avoid subtasks from duplicating when creating a project from a template - #2
She has also provided a workaround that might be helpful in the meantime.
I hope this helps Sean! But please let me know if there is anything else I can help you with!
