“Titles & Meta” settings

Dear Support,

I am using WP traveler theme (travelerwp.com) where there are multiple services/sections in the website.

I am trying to display the “tour categories” as a variable in the Meta Title Tag. I’ve tired to add the following codes %tour_categories% %tourcategories% %categories% %tour_cat% % %customterm(tour_cat)% %customterm(tour_categories)% %customterm(tourcategories)%

However, non of the above works. Also, I have added the “Tour Categories” as Primary Taxonomy for the tours section.

Please advise, what is the right variable? for “Tour Categories” to be used in “Single Tour Title” filed in Rank Math “Titles & Meta” settings. In order to have the “Tour Categories” part of the Meta Title of each tour page.

Thanks you in advance for your support.
