The colors on my calendars are working properly on my devices.  Not on icloud.com. The colors are wrong (really light hard to see now that the events are in the color). I selected edit, clicked on the currently displayed color (to the left of the calendar name) then selected the color that is on all of my other devices. After 5 sec it switches back to the color it is on now.  How do i fix that?

Thanks in advance.
