Hi Sheldon,
Thanks for your update.
We have validated your query and when we try to export GroupCaption aggregate we face the reported error at our end. So we logged the defect report “Aggregate Text Align is Incorrect when Export Grid with Group Caption” for the same. Thank you for taking the time to report this issue and helping us improve our product. At Syncfusion, we are committed to fixing all validated defects (subject to technological feasibility and Product Development Life Cycle) and will include the fix in our upcoming patch release which is expected to be rolled out on or before the mid of March, 2022. Until then we appreciate your patience.
You can now track the current status of your request, review the proposed resolution timeline, and contact us for any further inquiries through this link.
Kindly revert us with further details if the above case is not your reported scenario.
Regards,
Monisha
