I forked a repository on Github, added some changes to a file, ran lint and tests, committed to my repo, initiated a pull request, conversed w/ original author, pull request accepted and combined into original repo. So far, so good.
Now, I've added changes to another file, committed (linted, tested etc.), and went to Github to initiate a new pull request, but the list of past pull requests on the repo shows 0, and when I click the "New pull request" button, it creates a pull request containing both files.
Clearly, I've missed a step between 1 and 2. Could someone clue me in to what am I missing? Do I have to re-fork the original repo?
