unsolicited redirection

Unfortunately my ticket on your platform support.rankmath.com has not been answered so now I open it here waiting on this channel I can have a response from you.

I am building a site and everything was perfect until my fourth post is redirected to a page which I have not indicated in my redirects section, in fact, being a new site I do not have any redirect.

Specifically the url https://nichupte.com/tours/tour-atvs-cancun/ (post), redirects to https://nichupte.com/tours/ (page)

This is strange since the 3 previous posts have the same structure / category and works without problem.

Hoping to find a solution, in advance thank you very much.
