PowerPoint chart deleting data

Question

Took an existing PowerPoint slide with a chart, copied it. It had a single column of data, edited the data to include a second column of data. Chart updates to show both series. Save file.

Click on edit data again, and the second column of data is gone and the chart reverts to showing just a single series of data.

File is being opened and saved over a network (VPN to office). But it's not showing any errors with saving the file. The issue persists even after saving and copying the file to send to others to look at it.

Answer 1

Luke's video is showing exactly what we are seeing as well. It is intermittent, but when it happens the chart will show one set of data and when you go to edit will show a different set of data and immediately update the chart. We're using bar charts is the only real difference.

So the Powerpoint will look fine until somebody goes to make a change (hide a set of data or go to add additional data), and suddenly all the data is wrong.

All our instances of the error (that we're aware of) were from one computer. We did an online repair on July 9th and so far haven't seen it appear again.

Answer 2

I am having the same problems as described above. I've run the online repair, updated to the latest version and still have the issue. I update a chart with new data in the excel file and save it. When I reopen the chart, the new data is gone. As previously stated, this is an intermittent problem, doesn't happen on every chart but happens often enough.

Hi All,

As the issue is happening randomly, I may not be able to reproduce the issue in just few attempts. Since you have tried updating, repairing Office and issue happens on multiple Excel workbooks, I will suggest you please contact your tenant admin, so they can contact Microsoft support. We would really like to help, but we don’t have an escalation channel to escalate this request.

Once you reach the assisted support for the request, they’ll help you find the root cause, they can even involve related resources, if required.  To create support ticket admin can go to Microsoft 365 Admin center>Support>New service request. You may also refer to Contact support for business products - Admin Help.

Besides, from your end, if you have the Feedback option available, please consider clicking File>Feedback (or click Help>Feedback on the ribbon) in your Excel app to send feedback directly to Product Team. This will have more impact on the Product Group as the feedback is directly coming from the customer.

Thanks for understanding.

With sincerest regards,
