Column names are not displayed when we try editing kreport

Hi,
The issue is on kreport v4.2 when the report is created for Grant or representative module, on the creation it shows the column/fields on that module, But when tried editing the newly created report the fields are not shown only happening with Grant and Representative modules for others it’s fine.Screenshot (3)|261x395

Attached screenshot for your reference.

Rohit

In which CRM in which version do you run KReporter 4.2?

Its CE version of SugarCRM

Please open browser console and on network errors. I guess there is some request / response error. Would be helpful to see that.
