css - Why does my marquee have a giant empty space after each iteration?

Question

Basically, it'll go through the rotation and once the 8 leaves it just stays blank for a while and then the animation resets. I want it to continuously scroll without any breaks but I can't figure out how. I have added extra list items to see if it shortens the wait time but it doesn't seem to. Thanks for your help.
