LG G4 Keyboard - "Done" button next to "Delete" button- How to change?

[AC Question]

I have an LG G4. I have recently noticed a button called "done" in the bottom right part of my keyboard. Right below the backspace (delete) button. I do not remember this being there since I've had it, I thought it was the "return" button.

Clearly having a send button right below the delete button causes you to accidentally press send when you mean to press delete. Anyway to fix this?

Unfortunately what I initially type out is not always what I want to say, especially when I am drunk.

Thanks.
