How can I reset colour after Proof Reading plug in?

I used the plugin for parallel fifths and octaves on a piece. It found a few, and coloured the notes red.

Then I altered the piece and ran the test again, which found no parallels - but the notes were still coloured red from before. I could probably have avoided this by doing a complete revert, and then editing, but it was easiest to just edit the bars marked with the red notes.

Now how can I get the notes back to normal black?
