This isn't something that has been reported or should be expected. Although, it could be derived from a number of different settings. For example, custom styling might impede with the grid generation.
With that said, I would be happy to review the grid. Are you able to attach the Markup, Code-Behind, any Scripts and Data Source(s)? Note that for the data sources, see the Import and Export Database as SQL Scripts documentation.
Alternatively, I can convert this thread to a support ticket which will allow me to investigate your code with confidentiality.
Please let me know. Thank you and I look forward to your reply.
