PPTX showing headers when ExcludeFonts

Hello,
I have problem when I display pptx files. The problem start with when I add
viewOptions.ExcludeFonts = true; to Startup.cs.

But I have to add this because We had problem with displaying turkish characters in files so support answer with this to us “The working workaround would be setting ExcludeFonts the property off HtmlViewOptions to true. When this setting is enabled no fonts will be included in the output pages.”

So now I have new issue like showing unnecessary header in pptx. How could I solve this?
