Huge discrepancy on SDL word count and PPT Properties word count

HI Everyone,

I notice a HUGE discrepancy between SDL word count (2643 words) and PPT word count (1814 words).

On Project Settings / File Type /PowerPoint/Common, I already uncheck all the checkboxes that could cause this, such as Master view, Headers and footer, Notes, Hiden content, Alternative text, Hyperlinks, Comments, Embedded Excel charts.

Can you help me find out why this is happening?

Also I notice that PPT fo Mac and PPT for Windows present a slight difference in the wordcount.

My best,

Daniela
