menu and tab section

Hi,
I have a problem on this page: https://leagrowingpeople.com/who-we-are/

if I enter “our story” from the main menu I can enter.
But if I am already on the “Who we are” page, for example in the first tab “our team”, and I want to go to “our story” from the main menu, I can’t access, why? That is, if I am already inside the “who we are” page and I want to move using the main menu to go from one tab to another I cannot do it.

I also add a video to better explain: https://monosnap.com/file/pf0jZRJFtWvvFFP1qXzrz7mZwuB4RF

I hope the problem is cleared up.

Thanks for your continued support,
Manuela
