Order Comments not working properly.

I have installed Fast & Easy Checkout, and the module itself appears to be working fine. The issue I am experiencing is that the order comments section (where the admin may add notes for the customer) is not working properly. The default for the comments box is to email the customer and allow them to view the comment in their account. Regardless of which option I select the comments are always emailed and viewable.

There are often times where I want to add hidden notes just for the staff to view, now this is no longer working. Does anybody have any insight?
