Reusing IX2 doen't work properly


I have a hard time with IX2. I established IX2 for elements and it worked good, as I intended. Then I copied the elements few times and I changed IX2 to class - only children in order to reuse the interaction on all boxes.

The issue is that the interaction is different now, it is not the same as I designed. When you see “Digital Marketing” those boxes should have a smooth interaction, triangles must go in different directions and links should appear smoothly.

Why is the IX2 changing when I use classes?

Here is my public share link: LINK

How it should look:

I guess it’s because my IX2 affect many elements within the same class. Is there a way to reuse this IX2 without manually recreate classes?
