Set Color to List Reverts Back to Plain Color#1396

When I choose to set the color for a list, when I refresh or go back to the taskboard at later time or the next day the list is no longer one colour it has gone back to a plain color.

using Vivaldi browser. cleared cache. still happening

I have many original/older lists on shared board that maintain their set color, but new boards and new lists do not hold colors that are applied. I am using Chrome browser, have logged in and out and cleared cache and still having same problem.
