Both Master and Parent pages?
I went to make a change to a Parent page (previoiusly Master page) in one of my documents that's a member of a Book Panel. I made a change in the Parent page of my Style Master document and synced the Book Panel. It didn't make the change in my other documents. Looking closer at my Master Pages panel for the document, I see that I made the change in the Parent page but not the competing Master page: I have both Master and Parent pages which seem to be duplicates:

Now what should I do? Thanks for your thoughts.
Update: after a delay of a minute or two, and with a screen refresh, the change propagated to all of my documents.
Still, should I delete all of the Master pages?
