Capture Bookmark with Export Bug

Seeing an issue capturing the state of the workbook using a bookmark on one page and trying to export to pptx a second page with the same bookmark.  This causes the second page to print as if it were the first.  

Example:

• Workbook has 3 pages:  Page1, Page2, Page3
• Slicers are linked on all 3 pages.
• Change the slicer on Page1
• Capture the bookmark state
• Call Export API with 2 pages (seperate objects in the pages object) and pass in the same state string for both Page1 and Page2.
• Result is a PPTX with 2 pages.  Page1, and Page1 duplicated (but with the layout of Page2).  Page2 never exports.  Very Odd and seems like a bug.
