menu links do not work on new pages!!!!

Hello to everybody
New in the wordpress world and in this forum, so be patient for my requests!
I’m building our site with an Enfold theme … being a landing page developed vertically, the various areas “services”, “portfolio” etc. are custom links.
I created the “BLOG” page that appears on the menu but not on the site.
all the menu links lead to where they should … except when I enter the BLOG page …
the menu buttons, from the new page that I created, remain inactive …
how can I tell the menu to bring the same links even when I make new pages ??

thanks a lot
Good job everyone
Carolina
