Flight Considered Accelated

I’m flying C414AW and today I had the second flight considered accelarated. Average ground speed was 143 kts, based on Aviatife flight data, so I’m not sure why was it considered accelarated.

Accelerated flights mean that you sped up the flightsim. You can speed up time in the sip to x2, x4, x8, x16. And if you are on long flight that is very useful.
But aviatife keeps track of that so if you have to wait for next flight until the “real time” the first flight should have taken have passed.

But I did not accelerate. Something went wrong on this acceleration detection.
