Can’t show Product Table on Page

I have created a Product Table.

But when I add the Shortcode on a Page and view the Page, the Page is empty.

Here is the Shortcode on a Page— https://prnt.sc/-1zmwCoAo_z7

But the Page is empty— https://rejuvenate.ng/bulk-order/

I guess the problem is that there is no Documentation, so I don’t know what to do, and how to set up a Product Table with WPC Product Table plugin.

Can you please show me what to do, so that I can have a Product Table like this one– https://demo.wpclever.net/wpcpt/

Needing to hear from you soon.

Regards.
