Automatically marking orders complete after purchasing shipping label

I was unable to post a page link because it has to do with an order prior to purchasing a shipping label.

My issue is that previously when someone would place an order, I would go purchase my shipping label, prepare the package, ship it and only after it was dropped off at the post office would I come back in or use the mobile app to mark the order as complete. Recently I had a few orders and I noticed after dropping the package at the post office and attempting to go in to mark the order complete, that it had already been marked as complete. I later noticed on another order when I was purchasing my shipping label that there was a checkbox to mark the order as complete, and the box was checked. I never checked that box. I am guessing that this is from a recent update that this is now checked by default. I checked in the settings to see if there was somewhere to set a preference for that, but I did not see anything. Am I missing something?
