In Interstellar when they were on the water planet, every minute they spent there, several days passed on Earth. From outside observer’s point of view from Earth, everything happening on the water planet was in slow motion. Why isn’t it the other way around?

I mean, it does not really slow down time?
It’s more stretching time, speed is closer to slowing or speeding up time, depending on the observer.
The best way to visually experience this is by clamping a stretchy to a circle, be it rubber, or nylon or spandex or w/e, heck even normal cloth could showcase this well enough.
Take a ping pong ball and move it across, that is time without gravity, because gravity makes time last longer.
Put something heavy in the middle, and now the pingpong ball, which represents time will travel in a curve, this curve is our perception and experience of time, the greater the mass, the greater the curve.
Now lets say the heavy object you used was an orange for earth, then for the water planet, it would be 13 pyramids of giza.
