When I choose a category, an error appears in the JS console SyntaxError: '.catZellkultur_&_Verbrauchsmaterial' is not a valid selector
The error occurs when you use the special character in the name of the category. Mageplaza Shop By Brand js lib used for filter does not allow the special character.
Please try with another name without a special character.
