isnt the whole point that if you are quickly serving someone can close your ticket so that when you log back in the ticket does appear so you can settle it as you’re still serving the customer? switch user is setup for multiple users using the same terminal so they can all use it to serve at the same time without the orders being “lost”, simply log back in, order appears so customer can pay.
If you want to close ticket and then when you log back in it doesnt open again if you dont need to settle it straight away you can use ticket tags to setup a parked sale system or bar tab, ive just posted how i have this set up. have a look here to see if this would help you
