Form not submitting on some cases?

Form not submitting on some cases?

Hi Zoho, 

I have a specific form (Import Data for on my app) that when checking some specific options on checkbox field, it is not submitting properly-

I get a message that data was submitted, but the "On Success" script on On Add -> On Success is not processed-  details that are supposed to be updated are not updated, and openURL command is not processed either, I stay in the same windows with the form reloading again.

This happen 'hen "Section" field is filled with "Loan" and Insurance_Sub_Sections contains "Insurance details"

In all other cases even with other checkbox marked in the same field, script is working properly! 

Will appreciate your help with this one...
