Looks like you’re setting up the wrong category, so it doesn’t show tours by category.
I did a reset for you and now it’s working properly.
1. Please do not delete Booking rules, deleting these Booking rules may cause errors
2. Booking Categories: you just need to create a category category for all your tour bookings. This is to distinguish it from the hotel or event category if you want to add
3. You need to create Taxonomy as Category or any 1 taxonomy like a category to categorize tours by this category, then add taxonomy for the category you just created
4. When creating the booking objects, select the taxonomy above to classify
5. When creating a page, to classify tours according to the taxonomy selected above, you need to set up the All Items widget -> select Taxonomy to filter the tour bookings.
Please check your tours and pages, I have done a complete setup for you
