Horizontal scroll scrolls down too


I was doing an horizontal scroll interaction for my portfolio and something is off. I got the section to scroll horizontally but it scrolls down at the same time, it doesn’t stick until it’s come to the final ‘frame’. I guess it’s something with the ‘sticky’ position but I don’t know what… If someone could help it would be great.

Thank you.
