The code conflicts with another code (the same one, but changed)

Hello friends. When I plug in the code, it works and everything is fine, but when I duplicate this code, I slightly change (color, size, animation time) and re-insert it on the page along with the first code - they start to conflict with each other.

Look at the picture. This is the code that I inserted first and did not duplicate. When I duplicate the code, and then in this code I change the text size parameters, the color and the animation time - what happens is what you can see here: http://bogdans-stellar-project.webflow.io/

The parameters of the first code seem to fly off. Tell me please why?
