One planet (Gatria 3) has low and high gravity at the same time. Bug or feature?

Go home, gravity, you are drunk.

AFAIK it shouldn't happen. If you can, upload a save to allow devs look into it.

I suppose that's because Anomaly44 doesn't have <PlanetFilterNot>PlanetAnomaly36</PlanetFilterNot> on its filtering condition.

Yes, it was not supposed to happen like this in design. And it does seem strange when you think of this combination as the gravity being high and low all over the planet at the same time, as opposed to high in some places and low in others. For example, the gravity of Earth's moon is higher at the south pole, and earth's own gravity is now uniform in all places either. Of course, in our reality these differences are very small (though strong enough to disturb satellite orbits), but I imagine that in the Endless Universe, these effects might be amplified by Dust.

I encounter that situation once as well, thought it was just me.

This one irratated me too, so I did this (see below).  Not quite tested it yet, but hopefully it will work.  Huge/Large = no low gravity and Tiny/Small = no high gravity and Medium get both still:
