Default Climate settings not saving after battery reset

Hi everyone!

I have a 2015 Lexus Rx350 with ~57K on the clock. I disconnected the battery for ~10 min and reconnected in order to clean the terminals, and my climate control has been acting up ever since. It won't retain the settings after I turn off the car. For instance, if I have the A/C on LOW and turn off the car, it'll revert back to A/C off and 75 degrees the next time I turn the car on, which is possibly a default setting? The A/C works fine, it's just a pain that I have to navigate through the menu every single time I start the car to turn it on during the summer. It's odd because everything else is the same (ie. memory seating, radio channels, etc), only the climate setting is "reset".

Any ideas are appreciated - thank you!

Personal climate settings are linked to the detected key fob. Any chance multiple key fobs are present at the time?

Only 1 key fob was in the car when this happens (same one I always use).

Oddly enough, it seems to be working fine again. It took a couple days of starting and driving the car after resetting the battery to get it working properly.

Thanks!
