Description of the problem

A view of its moon from the planet shows it to be very large, but when the player is on a moon, the planet is too small to see.
And this problem is more apparent in gas giant planetary systems

↓when player on a moon, the planet is so small that invisible

↓In the selection interface, the satellite appears enormous

I don't know if this is a wrong of planet size I didn't find any adjustments in the official instruction set or configuration tutorial for the size of the planet itself (not the distance) , so I thought it might be a bug.
