Hi Marius W,

I have worked with the sample code and sample presentation file shared by you and have not been able to observe the issue while using Aspose.Slides for .NET 7.8.0. I have generated the presentation file with your code and I am also able to edit Ole frame data using PowerPoint as well. For your kind reference, I have attached the generated presentation as well. Please try using the latest version of Aspose.Slides and Aspose.Cells on your end.

Many Thanks,
