Mac print dialog box gets reset to off?

Hi -- appreciate any help -- running Windows 7 Ultimate on a Macbook Pro with Parallels Desktop 13 for Mac Home Edition.
Things were just fine until about 2 weeks ago. There was an update for Parallels and I don't know if that caused the issue, but three times now the

Actions--> Configure--> Hardware--> Share Printer--> please enable the " Show page setup before printing " is un-checking.

I have the lock clicked so in order to change it back to show page setup again (which I must do in order to select 2-sided because I turned off 2-sided printing at the CUSP level on the Mac), I have to click the gear for the settings, click the lock, enter my username and password, check the box to show the page setup, then check the lock to lock it again. I've done this several times now so I know it is happening automatically.

Is this something I've accidentally done or is this a mistake in the latest build or ??? Any other help appreciated.

Most of the time I don't need to have the print dialog but for anything other than ordinary default printer settings ... so if I want to print specific pages, if I want an envelope, if I want to print double-sided ... anything other than default must be set on the Mac print dialog or it just ignores the Windows settings.

looking forward to your thoughts. thanks much.
