I'm using the version 3.6.4 of Atahualpa Theme.
The webpage is http://tamboresdelunamora.com.ar/ps/
I decided to show only static pages on my webpage, so first I wrote all the pages, and after that I began to configured both menus: the horizontal, and the vertical (lef side menu!).
In the horizontal menu I blocked some "pages" with the function "ATO-> "Menu 1 (Page Menu)" -> Exclude pages from Page Menu Bar" puting here the Id of each page. It works perfectly fine!
The problem appears when I put over the option "ATO -> Style & configure SIDEBARS-> LEFT sidebar: Don't display on Pages: " the page's ID number to block.
I tried to block the pages with Id number: 146,148,128,124,138,126...
But those pages still appears on the left side menu...
As I can show in this image:

This is the view of the configuration menu

I read a lot of posts in the forum but even when the problems seems to be the same I didn't fine one case as mine...
Could be a combination of misunderstandings with the configuration because also I don't want to show the "home" page (the page ID 128) in the left side menu but it appears below the page 126.
I don't use any widget.
So I know something is wrong with my configuration but I could find the solution.
In the "ATO -> Style & configure SIDEBARS-> LEFT sidebar: Display on" configuration I had to activate the options: Front Page and Page (pages)... because If I choose only the Page (pages) option (as I read in a couple of posts) the webpage doesn't show any left side menu...
As you can see in the this picture...

I also read a post where JuggleDad suggested to install custom tax but It didn't work for me...
In another post JuggleDad suggested to use a category filter but it didn't work either...
If you see in the link I put you you will see the same "pages" in the horizontal menu, than the vertical one (left side menu!)
Thank a lot for your support!
