Category list in mobile version

Hi,

thnx for your reply. I have a problem with category menu in mobile version of the shop... Everything is fine on the computer version - I see category menu on main page and on subcategory pages too. When I go on dlaelektrykow.pl on my mobile - I don't see any category menu or any filters (nor on the home page, either on the pages of subcategories).
Check the attachement.

Thanks for your help.
