Hi guys, please i need your help

We are using TUTOR LMS and i according to totirials set up a COURSE BUNDLE – with 7 paid courses in it. But the problem is, that the course bundle i can see is only in the main page here: https://www.llacademy.sk/kurzy/?keyword=&tutor-course-filter-type=bundle&course_filter=true&loop_content_only=false&column_per_row=3&course_per_page=12&show_pagination=true&current_page=1&action=tutor_course_filter_ajax

I CANNOT SEE the details of the course: https://www.llacademy.sk/course-bundle/kompletny-balik-kurzu-stante-sa-specialistom-na-verejne-obstaravanie-2/

Can you give me any advice what to do? Thank you
