Data disappears from view when 38th input field is created

Data disappears from view when 38th input field is created

This is the form: http://creator.zoho.com/iscbrasil/pains/form/1/
There is some data loaded in the table behind.

When I create a new field in "Pain 06" all the data disappears from the view. If I delete the last input field, data reappears.

Any idea ?
