[SOLVED] Sidebar missing on "Site Menu" docked Pages

[Testing the latest dev version litecart-2.6.0-dev-f34779]
I noticed that pages assigned to the "Site Menu" Dock aren't displayed with the left side menu . Is this intentional?

No experience with 2.6, but in 2.5.5 you should assign it to "Dock in customer service"

Thank you jackmaessen for your answer! 
I'm already using 2.5.5 but wanted to ask if this setting will be changed in the new version 2.6.. 
I am working on my template to publish my IT online shop with the new version 2.6. in production. I would like to change a few things and would like to use the specified settings.

There is a change in Pages where it's no longer possible to dock a page to multiple places.
There were several reasons why this changed. Mainly duplicate content and confusion.

And if you make a page standalone in the site menu, it doesn't have the information links.

Thanks for your clarification. However, you point out something that I have never been able to enable: the presence of a single page in multiple menus. I always thought it was not possible!
From many versions, each individual page could only suggest one menu choice. I did not know this possibility existed. As you can see in the screenshot, my few pages are clearly assigned to a single dock.

OK; fine! So it's a deliberate decision. But my question was that when you click on this element, this page doesn't follow the layout of the other pages. I imagine this has to be enforced by adjusting my custom stylesheet.

That sounds like a custom stylesheet thing yes.
I did not understand if you need anything else done.

No problem; obviously my English is bad. I apologize. I have since solved the situation by adding an integrated stylesheet (.card) to the HTML of the same page. I am working on the new version and will see if I can think of anything else.
Thank you for your answer.

Yes .card is part of 2.5+ and is the successor of .panel. This industry change is Bootstrap setting the trends.
