Hi MaciejYou,
Which ones? I see “Tabata” and “Pilates”.
I have one events on column “sobota” at 10:30 to 11:20.
Could you export your data via Timetable > Import / Export menu. And send xml to [email protected]
I got the same result as I see on your website.

If you want to add more events to the table you can either add new shortcode via shortcode builder or add Event->ID to ‘events’ parameter of the existing shortcode. You can display all events by selecting only columns in shortcode-buidler popup.
I do not see any event in column “sobota” at 10:30 to 11:20 in your exported data.
