Planetary Gears - Is this offset correct?

I just used a Feature Script to generate a Planetary Gear. I also designed one by myself based on the Spur Gear Feature script. Both show the same effect. There's an offset between the Sun and Planet gear, but there's no offset between the Planet and Ring gear. SunTeeth=9, PlanetTeeth=9, RingTeeth=27,
Is this correct from a mechanical point of view? Or is using spur gears just wrong for designing planetary gears? Or is it supposed to be this way?
In the end I would like to 3D print the gear, the Sun/Planet gear offset will help me to get the tolerances right, but the not existing Planet/Ring gear offset could be an issue
For reference: My FeatureScript containing both designs
