I cannot delete invoice

I recently created an invoice, the invoice is a draft one and not included to my recent VAT return.
Because now I have integrated my paypal account to my quick File account, I have a duplicate invoice… I would like to delete the first invoice but when I click on the relevant links it does not work.

Please can someone help me?

Thanks,

Lars

I’ve located your account, do you have the invoice number please? I will take a look for you.
