2017 caravan gt lock?

Used to be able to push button in rear to unlock and open sliding door. Brought it in for oil change today and now if a rear passenger pushs button while doors are lockked the information display says unlock doors to open. I know its petty but a pain in my a$$. How do i get it back to unlocking and opening by push of the rear button. Thanks

There is a rear lock/ window child safety switch on the driver's door between the lock/unlock switches, and rear window switches. Push the button.
