John, in S2 you want to select the object by clicking on it and then click on the little icon to get the context menu where you choose Edit Properties.
That opens a menu similar to the one used by TLR. You can adjust the doors there and click save changes. Now by default you are paused in surveyor so you won't see any changes until you unpause using the menu. For some reason, the P key doesn't activate the changes in TRS22 PE. You have to unpause in both Surveyor Classic and S2 to see the changes happen. That is likely what was tripping up the OP.
