How to change default slug in the middle of the permalink?

Hello,

I've faced with one issue and I have no idea how to solve it. Situation:
I bought the template for WP and in this template there is a section "project".

I created a project using YOAST for SEO and permalink was: website.com/project-view/my-project
(Yoast in its module writes it as website.com/my-project) but on the website people see 1 option.

Question?
How to make it website.com/my-project without "project-view" or even maybe is it possible to rename…
