It looks like the issue is your climate control screen. You already have display issues as shown and over time it will get worst. What I think happen is your AC icon is no longer properly displaying. You will need to get it fixed if it annoys you or replace the unit. As long as your AC button works and you are getting blasted with cold air you're good. The reason why Auto display comes on when AC button is pressed is that's the default setting to quickly cool the air. If I recall correctly my car does that too and the fan/temp? adjustment will turn it the auto climate control.
