Changing delay of "bouncing arrow animation" sets color to black

I added a hero with laptop bloc. At the bottom of the bloc there’s a down arrow. I changed it’s color to another color. Then I changed the delay. The color of the arrow changes to black.

The color of the arrow on the page is block is still correct. But if you publish or preview the page, the color is black and not the color I set it to.

Also it seems that the order in which I add the color, change the animation delay, etc. plays a role.
