Reactjs – Bit.dev preview not rendering in preview tab, but in overview page

in my (freshly setup) local bit.dev environment, my component wont render under the preview tab section. The preview seems to work in the "Compositions" section in the preview tab.

Button Component Code

import type { ReactNode } from 'react';

export type ButtonProps = {
  /**
   * sets the component children.
   */
  children?: ReactNode;
};

export function Button({ children }: ButtonProps) {
  return (
    <div>
      {children}
    </div>
  );
}

Button Composition Code:

import { Button } from './button.js';

export const BasicButton = () => {
  return (
    <Button>hello world!</Button>
  );
}

Overview Tab:
