Sometimes it confuses me that a change has apparently not occurred when really it is just that my browser hasn't refreshed a page or I've hit the "back" button and am looking at an old page.

If that happens again, try exiting your browser; then restart it and go to the schedule page and see if perhaps it now doesn't show it correctly.

You could also try just right clicking and then selecting refresh. That seems to work better than hitting the refresh button on the browser status bar for some reason.
