Unintentional fullscreen with packaged/built projects

Hello. I’ve had this issue with version 4.16 and I believe 4.15 where when I package a project it will fullscreen if I don’t use a command to set the resolution. If I DO use a command/command inside the level blueprint, it works, but once I toggle fullscreen on and off, it just maximizes the window. I tried looking for some sort of fullscreen settings but I found nothing that works for my issue. This might not seem like a big issue, but it’s very irritating to know that I can’t play my executables without running into this issue. Thank you for your time.
