I switched to Aspose.Slides 16.1.0 and I can confirm the issue reported above is not present any more. Thanks you for fixing it.
However, there is new issue with both of the attached presentations. When I open the presentations in PowerPoint after open/save via code, this is the message I get:
PROTECTED VIEW Office has detected a problem with this file. Editing it may harm your computer.
It’s good to know that things are fine on our end. For the new issue reported by you regarding presentation repair message, I request you to please share the complete PowerPoint version used on your end along with generated presentation so that we may investigate that further on our end.
