if you want to put your mind at ease then in your Preview page, copy the yellow highlighted address and go back to main window of your wallet, go to Addresses tab (if it is not visible from menu select View > Show addresses) now that you are here press Ctrl + F to see a search box appear at the bottom, now paste your copied address here. the list above should be filtered to only show this address. if you don't see it from the two drop down boxes for filtering select Change in first one and ALL in the second. you should see your address here.
...or you can go to Console (if you don't see it enable from menu View > Show console) and use the following code:
Code:
ismine("paste_your_copied_address_here")
this should show as true.if you don't want to use Change addresses go to:
Tools > Preference > (Transactions tab) > (uncheck the box saying) Use change addresses
