how to modify woocommerce account

Hello,
How do I modify the WooCommerce “My Account” page?

I used the brick templates, but there’s something strange: it creates duplicate content.

So I decided not to use the templates and instead created “My Account” subpages with WooCommerce endpoints, which allows me to modify each of the brick pages as I wish.

But something strange happens again. For example, for the “My Account” page,
I create my menu on the right, then my personal content on the left, and below it. I place the “Account-Page” element to change the page content; it works.
Then I start my “Orders” page. I copy and paste it, I change the personal content, but when I view the content on the front end, only the latest content is saved, and on all the “My Account” subpages and also on “My Account.”
It’s as if it only keeps one piece of content, whereas I want different content for each subpage.

I think I’m doing it wrong.
What should I do?

I solved my problem with this post WAIT: WooCommerce Account Page template acting weird

But I have a new problem because I’m using the WooAutomate and Woo Points and Rewards plugins.

And there’s no template for these two new endpoints.

So I created two pages for these endpoints. It works. The content loads fine on the My Account page. But if I add text content to these pages, it appears on all the “My Account” pages.

How do I create new templates like the ones already present in Bricks?
i filmed the problem:

I have a second problem in the video we see that when I click on a link in my menu a content loads I click a second time another content loads…
