Master Page not separating left from right

[Departamento5CB8]

Hello to you all, so i'm having a problem working with some master pages.

I created 20 master pages with 2 pages each and the header is differente in every master page.

When I drag a left page of my master page to the document the right page appears too but I have other master page that when i drag the left only the left appears! 

What is making this happend? I need it to be individual so i can use a diferente master page in each page.

Hi Departamento5CB8,

check on R master if all the elements have contact with both master pages and crossing or even touching the spine.

Hi, that was it, i thought it was only in the left page but there was a 1pixel in the other page that's why it was doing it. thx for the help!

It could be a problem with how the master is set up but if that’s not the issue, instead of dragging the master onto the page, have you tried highlighting the page first, then right-click and choose to apply a different master to see if a different master can be applied to that individual page correctly? If so, try to reapply the master page you want.

There are 2 moments:

1. Better to apply masters using the Apply window (Right-click on the Pages panel or Panel menu > Apply Master to Pages > choose the master and the page numbers). 

2. Check the master elements. If some of them affect both the pages in Master, they will appear on both sides of the spread in the document.
