When I open and save the attached presentation, the space between bullet character and start of the text is trimmed. Please take a look at the attached screenshot.
I have observed your comments and have worked with the file shared by you. I have not been able to reproduce the issue on my end. However, a warning message as “Office has detected a problem with this file” is appearing on my side. Please report if you see the same message when you load and save the presentation on your end. I have attached the generated output presentation for your kind reference. I request you to please try using Aspose.Slides for Java 15.9.0 on your end and then share your kind feedback with us.
With Aspose.Slides for Java 15.9.0, issue with trimmed text is gone, but the warning message “Office has detected a problem with this file” exists on my side too.
