Horizontal Scrolling not scrolling

Hey there, I’m having a hard time with horizontal scrolling.

I used the preset created by Readymag, but the images move only a little bit and then the animation stops working. I haven’t changed anything in the preset, and as it says, the images should move from the right side to the left side of the screen. However, it doesn’t even let me see any of the images that are off screen at the beginning.
I’ve watched every kind of tutorial and followed all the steps, but the problem persists, I’m not sure if it’s related to a setting that I might have missed

make sure your page is long enough! Otherwise it would be helpful to see a link to your project
