My ticker will sometimes play through all the items and flash the first item again at the end for about a second before transitioning to the next Layout. It looks like a glitch.
Example: Item 1 (10 Sec.) > Item 2 (10 Sec.) > Item 1 (1 Sec) > Next Layout.
Duration of 10 Sec. is set to per Item as the amount of items available can vary.
