Excel header-stamp overwritten when converted to PDF

I’m working on an application where you can upload an excel-file which then puts a stamp on it and afterwards you can - if you will - convert it to a PDF. The problem is that the stamp gets hidden beneath something that seems content-related (the content of the excel-file) which should not be able to happen.

I’ve attached a file which shows the header-stamp when zoomed in to 300%. What you see is actual text which lies beneath some cells “filled” with white. Any preview of the excel-file and other pdf-converters works just fine. How am I suppose to fix this issue?

I’ve just found out that by reverting to an older version of Aspose.Cells (7.3.2.0) it got fixed. That means the newer version 7.5.1.0 caused the problem.
