Why two time same category show in chart even i have one time entry in data source?

Hi Aspose Team,

I have generated column chart using latest version of Aspose.Slide. I have attached PPT that i have generated. In PPT you can clearly see chart having 2 categries and 3 series but when you see excel of data by right clicking on it there is only one entry for category that show in chart. So why chart show same category two time?

@sdtechsupport.sirius,

I have observed the presentation file shared by you and request you to please first try using Aspose.Slides for .NET 18.5 on your end. If there is still an issue then please share the working sample code along with source presentation file with us. We will be able to investigate the issue further on our end on provision of requested information.
