Duovalve causing me hot air??

Finally got AC back to my 95, however, the climate control is giving me problem. If I just turn on the A/C (coldest setting) as normal, I will get warm hot in the 2 center vent and hot on the 2 side vents. If I press the blue button in the center, I will get cold air (~45F) in the center vent, but still hot on the outside vents.

This is forcing me to shut off the outside vents and only uses the 2 center vents for cooling.

The evaporator temp (code 5)from the climinate control is showing 42F, so I know the system is not low on freon.

Is this a classic duovalve stuck open symptons?

Also my driver side temp wheel is all over the place. I move the wheel a slight amount and the temp can jump 10F, it is very hard to control temperature on the driver side. Is this common?
