When a customer leaves a comment on the quote page, it's not visible on the admin page. Does it have to be like this or I'm missing something?

To find the comment of the customer, on the admin sidebar, please go to Sale --> Quote management --> Quote History to see customer's comment. Please take a look here: http://prntscr.com/p0zygu
