Gmail Asana Add-On Not Adding E-mail Or Attachment

I’m looking for a way to add e-mail’s and attachments to tasks created for the relevant members of my team however its not working.

I am using the Asana add-on to gmail and creating a task (while checking the “add attachments” box) and once i click the “create task” button it tells me it cant attach the e-mail to the task and it goes out as a “task” with no attachments or link to e-mail… Could someone please help.
