Dear B Mooney
Thank you for reaching out to the Microsoft Community. We are happy to assist you.
Before we proceed may I know what version of PowerPoint you're currently using, because I tested it on my PowerPoint desktop app and was able to group and ungroup perfectly using this bar
Please refer to Group or ungroup shapes, pictures, or other objects - Microsoft Support - for detailed information on grouping and ungrouping in PowerPoint
Please give it a try and let me know your update. If the issue still persists, please provide a details screenshot of the issue and make sure that you hide all your personal information
If you have any other questions or need further assistance, feel free to ask
Best regards,
