The default "new_preset" always uses Nauvis's ratios, no matter which planet is selected. I think this was broken in an update?

The fix is to make a new preset, and delete the default. Then swapping planets works as intended.

Running into the same issue with Space Exploration installed, but creating a new preset does not fix the issue when you're on a different surface. Creating a new preset only works when creating it while on Nauvis. Creating a new preset while on any other surface returns this error:
