Because an AoA gauge responds directly with "relative wind"
Airspeed indicators respond to ram air pressure measured against static
pressure. Have you ever noticed that your airspeed indicator seems to
read higher in the winter due to denser air (assuming you live in a
climate with vastly different temps between summer and winter). Also,
have you ever noticed your airspeed indicator reads lower at higher
altitudes (due to less dense air)? AoA is accurate regardless of the
above mentioned differences.

Do you mean "for the same power setting"? Engines tend to produce more
power in cold temperatures than hot, so perhaps that would explain it.
In glider, what you might notice is your ground speed is lower (e.g.,
when landing) in the winter than summer, even though you have the same
airspeed indication.

It's not a problem - it's a benefit!
