Intray upload via email

I would send many invoices via email to the MYOB app uploads but when I went to enter them, many were missing. I went to 'more ways to upload, and generated a new email address. I click the copy button and it says copied but when I paste it is blank and I can not see it. I've tried pasiting to notepad, the email program and there is no email address copied. the new address is greyed out and I can't even highlight it to see what the rest of it is. I've tried on different computers and different users but it's all the same.

Can anyone help please?
