Reuse slides deleting slide number and footer

[PSSMargaret]

Hello All,



I'm new the forum. I'm using PowerPoint 2010 and am trying to understand why when I insert slides from another presentation by using Reuse does it delete my slide number and footer and it doesn't conform to the template formatting when the slides are inserted. The "Keep Source Formatting" box is unchecked.

The slide number and footer were created using the Master slide and work perfectly when insert a new slide layout.

Any help will be greatly appreciated.

Margaret
