Filters not working in Travel template

Hello, I'm trying to use travel template. The thing is filters are not working. Here is the AWS Link: https://s3.ap-south-1.amazonaws.com/travel-filters-amp/templates/travel/travel-results.amp.html

Please help me out!

Thanks in advance!!

Start by opening the linked travel-results.amp.html and reproducing the filter behavior in the Travel template. Identify which filter interaction fails and trace it to the corresponding source in this repository; done means the affected filters work as expected and the behavior is covered by a reproducible check.
