Problems extracting structured data

I’m having trouble exporting extracted data from a website.
The table has over 2000 rows displayed on a single web page. When using the Export Structured Data activity & checking the results in Excel, only 22 rows are visible rather that 2000+
When using the Export Data Table wizard, the preview is as expected & I’ve changed the ‘Maximum Number of rows’ property to 0 (so it should pic up on everything) but no luck.

Is there anything else i can do?

Thank you
