Hi,

Thank you for the reply. Yes, I'm using the transformer theme.

I think it's an Ajax update problem too, but I don't know how to update it.

For now, as a temporary solution,  I just refresh the page on add/remove voucher submit, and it's working fine. 

But I don't want to refresh the page to get my order data refreshed.
