Permalink structure issue

Hi there,

We are running into a critical problem.

The individual event page has the default URL structure as https://www.example.com/event/event-name-1/

Following are the settings on our client’s website:
The blog page is this: https://www.example.com/blog-page/
The permalink structure is: https://www.example.com/blog-page//%category%/%postname%/

The event page also follows this permalink structure so the events URLs are: https://www.example.com/blog-page/event/event-name-1/
I want these URLs should be https://www.example.com/event/event-name-1/ (meaning, event pages shouldn’t list under blog-page)

How to achieve this? Could you suggest a solution?
