Conflict with WC Bookings for guests

I have currently disabled the Cleantalk plugin because it is rejecting requests. On the page that I linked, clicking a date should bring up a list of available times. It works when Cleantalk is disabled (as it is right now), but if I enable the plugin, the request is getting corrupted (the “form” parameter doesn’t reach the server in the AJAX request). I want to exclude this form but even the “Form Signs Exclusion” setting is not working. Please help to make this work.

The page I need help with: [log in to see the link]
