Hi Angel,

I have worked with the presentation file shared by you and have been able to observe the issue specified. An issue with ID SLIDESNET-35992 has been created in our issue tracking system to further investigate and resolve the issue. This thread has been linked with the issue so that you may be automatically notified once the issue will be resolved.

We are sorry for your inconvenience,

Hi Angel,

I have tried opening the presentation in PowerPoint 2010 and it failed to open in PowerPoint even. The shared presentation is not a standard PowerPoint PPT document. It
looks like it was saved in another Ms Office document as an OLE object
and was extracted with some special tool. Can you please open the attached file in any version of PowerPoint and share the complete PowerPoint version with us. Please also share that how this file was created?

Many Thanks,
