Thanks @KoalaSat, I updated the maker form and searched the codebase for any other references escrow duration. I would gladly test the frontend but I think I may need some help with test data to fill out an order; or just advice on how to test the change. I'm not very familiar with the flow but the duration is likely set after the deposit. I'm not sure what ways you go about bypassing the step for local testing. Thanks in advanced!

Oh and I found a small grammar issue when I opened one of the files to update so I included as part of the pr; hope thats ok. I can split it out into a separate pr if that's helpful.
