WdInformation.wdVerticalPositionRelativeToPage gives different values in VBA vs C# - com

Question

I am translating a piece of code written in VBA to C# using Microsoft.Office.Interop.Word
What I observe that
p.Range.Information[WdInformation.wdVerticalPositionRelativeToPage]
in C# gives a different value vs. when used in VBA
p.Range.Information(wdVerticalPositionRelativeToPage) where p is the Paragraph object.
This happens whenever a shape is present on the page of Word document. I was wondering why this is happening? Is there something different in rendering of documents when document is opened via C# vs VBA?
PS - in both cases, word visibility is set to false.
Edit: Update - I tried to set visibility to true and I do observe differences in document rendering when Document is launched using C# vs using VBA. How do I fix this?

Answer 1

So I figured out the problem. My code was trying to access header section like this
foreach (Section sect in objDoc.Sections)
{
foreach (HeaderFooter hf in sect.Headers)
{
someFunction(hf.Range.Paragraphs, false, false);
if (hf.Shapes.Count > 0) // to handle shapes in Headers
{
someFunction(hf.Shapes);
}
}
}
For some reason, accessing headers changes the position of paragraphs in rendering causing the different values. To fix this, I now access headers as the last piece in my code. Hope this helps somebody.
