HI Oleg,
thanks for your replay. I found a “workaround” I created empty categories. You can try my problem with following URL: https://www.zweirad-fischbeck.de/shop/?filters=typ%5Betrekking-ecross-esuv%5D|variante%5Bmen-unisex%5D|groessen%5B11-cm,53-cm-54-cm-55-cm-56-cm-57-cm-58-cm-59-cm-60-cm-61-cm-xl-%5D
When I add f.e. 11-cm as a parameter to my URL, but 11-cm is not available as a category, then all other parameter 53-61cm are also not preselected.
