I couldnt find it.

I have the same issue. While Displaying the PropType table of a component in storybook, all the props from styled-system are shown as the type='other'.

All other custom props have their type shown properly.

I am importing the things as:

import { space, flex, flexBasis, layout, position } from 'styled-system';
import propTypes from '@styled-system/prop-types';

I am exporting the proptypes as:

BoxBase.propTypes = {
  ...propTypes.position,
  ...propTypes.layout,
  ...propTypes.flex,
  ...propTypes.flexBasis
};

Any help is appreciated.
