Greetings everyone!

I am one of the Local Desktop Support Techs, and I am having an issue with a user in excel. This user has multiple .xls spread sheets that link to one .xls master spread sheet with Multiple charts/graphs. The issue she is having is when she opens the master spread sheet it will display 5-10 duplicate charts/graphs over both of the original charts (like someone copy and pasted the same chart over and over on top chart), Any thoughts on how this can be fixed or explained to me so I could fix it.

PS: she is using Excel 2007
