Not working Add Multiple button

Not working Add Multiple button in Sales Invoice after updating values for billing type and it changes the format of item table making the add multiple button not working.

Billing type? where?

It’s worked properly in v15.

I think the billing type is custom, im new to erp, and currently using v14

If any code is applied then comment on it and check it.

I think the problem is whenever the billing type has value it affects the item table and the multiple button disappear and when it comes back by pressing add row button then its function is not working.

I’m not sure about your specific scenario, but I tested it by adding a custom field and checking with the latest version 14, and we didn’t encounter any issues!
