Visual Report Builder - No chart data to show

Hi,

I have created visual report builder for my forms. First it worked fine, but now it says "No chart data to show" (check screenshot). 

What is wrong?

Hello,

Thank you for your message, after checking your account I can see that you have a few forms, could you please let me know what is your form ID/URL? So we can make a clone and test the report, also are you seeing a blank pie chart in all of the slides or just one?

If you need any further assistance, please let us know. We will be happy to help.
