bullet points distance to text to big

Hi!

I have a problem with the bullet points, it only occurs within the accordeon. the bullet point are way to far left.

this is what i added in custom css, it works fine on other pages without accordeon:

ul.liste li:before {
    content: '■';
    color: #df6e1f;
}

what did i do wrong?

thx!
