SUN - ICAO rules
The sunrise and sunset times correspond to the passage of the center of the sun below the horizon (so when the base of the sun is 3 degrees below the horizon since it is considered that the sun has an apparent diameter of 6 degrees)
The hours of the aeronautical day and night correspond to the passage of the center of the sun 6 degrees below the horizon.
Night: Period during which the center of the solar disk is more than 6 degrees below the horizon.

So
when the center of the sun come up 6° below the horizon to 3° below the horizon (the top of the sun just appears on the horizon), this is DAWN.
when the center of the sun come down 3° below the horizon (the top of the sun just desappears on the horizon) to 6° below the horizon, this is DUSK.

Seems this is not the situation here at KNRD and all over the world.
If we can see a little part of the sun it is DAY.

Can you do something? But perhaps this fault does not exist in the professional version?

If we can see a little part of the sun, this is DAY, not DUSK, not DAWN.
You diseagree that?

May I have an LM answer?
Best regards
