Problem tracking reservations from Pages with Analytics

Hi Community,

We have a problem with the tracking in Google Analytics of reservations that come from Pages made with Yext.
Despite the fact that an appropriate slug has been inserted, the system is unable to highlight the path of the user who books through Pages: his reservation is inserted in the general ones that have the same thank-you page not allowing us to split between the two methods.

Has this happened to others? How can we solve it?
