Button icon animation delay

Question:
How can I fix an animation delay that I have not set?

Product:
Wix Studio Editor

What are you trying to achieve:
I’m trying to edit an existing Interactive Hover Section template. I want my section to have a black background, and the repeater items to be filled with white when I hover over them.
Upon hover, I’d like the color of the elements inside to change to black, which includes a button with an icon which I also want to rotate.

What have you already tried:
I’ve been able to successfully make everything work as desired except the color of the icon in the button has a delay that I did not set. I’ve created a custom animation where I’ve adjusted the relevant attributes (changing icon color, button border) and also set the animation timing to start at 0s and end at 0.3s. The border of the button changes fine but the icon takes a few seconds to switch.

Could this be a bug? Or Am I doing something incorrectly?

Have you tried to adjust the Easing to Linear in the custom animation timing ? Do this for the Animation and the initial state and elements will transition quickly.
