Master pages overlapping

[openskies2009]

I have a twenty page magazine with a two page spread. Three different masters are applied to different pages.

The problem I'm occurring is that even when I click and drag a blank none master over to a page, elements from a master that has graphics on it are still applied.

I have indesign CC, on a macpro.

Am I missing something?

By default master items applied to document pages are locked (unselectable) . If in your document they have stayed locked then when you drop a blank "none" page on top of its page in the Pages Panel the Master items will disappear from that page. If you have "unlocked" the Master items on the page either singly with the keyboard command (Shift-Command-Click (Mac) or Shift-Control-Click (PC)) or you've used the Override command in the Pages Panel pull-down menu then they have become at least partly detached from the Master (some Master Page control may still work on the objects) and will remain on the page when you drag a blank master over its page in the Pages Panel.

If you override a masterpage item it will stay on the page when you apply another master. So here I get different results when applying the B-master to spread 2-3 and spread 4-5. On spread 2-3 I had overridden the orange and blue rectangles when their master was A-Master, so they remain on the page when B-Master is applied.

An exception to the override rule would be Primary Text Frames, which you can use for running text between different masters.

Here I've included a Primary Text Frame, which will be sized to the A-Master's margins and automatically overridden and threaded on the 20 pages:

I can make a 2nd B-Master based on the A-Master and edit the new master’s primary text frames (a page can only have one primary frame).

Now when I apply a B-Master to an A-Master page the primary text flow is updated:
