Master page not applying to other pages

[JasperCat10]

Hi all, need some help please. 

My master page has some information in the pasteboard that needs to be on all pages. 

I have placed it on the correct layer within the 'Master-A' but when I click on to my page 1 and 2 (which both have 'Master-A applied to them) it doesn't appear.

At my wits end and have never encountered this before. I've had to cross out my client and company for protection reasons.

Thanks in advance.
