I just opened my shop on dream market for when I re-open around early february (i opened vacation mode for now), but for some reason people still place orders with me. Vacation Mode on dream isn't properly hiding my listings it seems? Any other vendor able to confirm this issue?
I had this problem as well. You need to go to the individual listings and uncheck the box under "Title" and "Orders". The box is called Listed.
I hope this temporary fix helps you.
