Tire Pressure

[X5FX]

Which tire pressure settings are correct (see attached photo)? 32/38 or 35/42

I recently had the tires rotated at the dealer, then immediatly left on a long road trip. I checked the pressure this morning after I returned and noticed the the dealer rotated the tires but didnt check the pressure, so I have been driving the past 1000 miles w/ 32 REAR and 38 FRONT pressures. Should I have expected the dealer to change this when he rotated the tires? I am pissed he didnt.

BTW- The reason I checked the pressueres was the TPM gave me a warning when I got in the vehicle this am...front right was low. I checked and it was at 27...drove to a gas station and filled it up and readjusted all the tires to 32.5/38. Just went out and checked (8 hrs later) and the front right is still 32.5...I dont understand how I lost pressure in the one tire, but now all is fine. Maybe its a very slow leak and the TPM just now reported it.
