When you see the reset icon above right on a video page, click it to bring the showreel back into the correct order.
The appearance of the symbol means that you've likely loaded the page from the front page "Latest Added" feed, from an embedded video, an RSS feed, Facebook, the newsletter, Twitter etc.
This can load videos into the player out of regular play order.
A simple click on the button will sort it, and return to the default page set up.
Click on the image below to give it a try.
