Remmittance Bank Account Support (Receipt Classes and Methods)

Summary

Empty Fields during the creation of the Remittance Bank Account

Content

Hi,

I need your help to solve an issue. I've already created a Receipt Class and a Receipt Method, but now I want to create a Bank remittance Account. I've entered the values in all the mandatory fields in the Bank Remittance Account creation page, but when I try to insert "unearned discount" and "earned discount" values and click on the two fields there are no values to insert. 

Have you an idea to solve this problem? 

Thank you very much
