Issue Replicating Project Templates in Production from the Sandbox Environment
I'm attempting to rebuild templates that I created within my sandbox environment but when I build them in prod the total project duration is completely off. I've included a screenshot below of the template I'm trying to recreate.

As you can see the development & review summary task says the steps will take 60 days in the sandbox but the same template with all the same tasks, durations, task constraints, and predecessors is saying it will take 112 days in production.
Would love to know if anyone has seen issues like this before! I've submitted a support ticket but they haven't responded to any of my emails : P. I'll close this question and include the solution if support is able to figure out what is going on before we can!
