Showing edit mode for messages

I'm working on a desktop UI that has a notes section which allows the user to submit notes and edit them afterwards. When I go into edit mode, the "save" button shows up, and I worry that it competes against the submit button (we're not doing a return to submit, so we need to have the submit button).

I can't decide if I should be turning it into a modal edit, or whether it's technically ok to keep the edit mode inline like this? I'm worried that the buttons are competing. Is there anything out there that does something similar?
