Thank you for contacting Telerik Support.
Can you send us the report that you generated with the wizard and tell us the exact label type that you chose - we need to examine the generated report. Also, if you have some other documents generated by another tool (i.e. doc, pdf, etc.) showing Avery labels, sending it for comparison will help us greatly.
We also have another question. Is the incorrect behavior occurring only in PDF? What happens if you preview the report with the WinForms Viewers - is it OK or is it wrong again? Thanks in advance.
P.S. To send us files, you will need to open a support ticket and attach them in it.
All the best,
the Telerik team
