Exception - 'ContentType string is not valid'

[AdamShakhabov]

Hi,

I am using both OpenXML and Spire Presentation to manipulate the presentation file. I found that on some slides I am encountering an exception if I save the file in Spire.Presentation and then opening it on OpenXML.

I've attached a sample pptx file and solution file for your reference.
