All good! The editor has a learning curve to it. It doesn't look like you've fully completed the walk through - I would highly recommend doing so as it will really cut down the difficulty in using the online editor.

I've made some further adjustments based off your additions and comments. You can see my changes here:

It may take several days for the map to update visually, but you can view my changes instantly by pressing "edit" after following that link.

Thanks for contributing to the map! Happy mapping :)
