In order to change names of a room go to Room Manager. Double click on this room to open it, then enter a correct name here:
The rooms in Bed View are in alphabetical order.
If your rooms have their own names and there are not in alphabetical order in real life, you can add a number before the name in the system to have them in the order you need. For example:
The rooms on Bed View will be in the order you see in Room Manager.
