Color in draft viewer lags one behind

[fitz-1]

When the color of a warp/weft is changed, the view tab lags one color behind when updating the color. For example, I click the color to switch it on the drafty, and when I click the color, the color that previously populated the box in the drafts updates to the view window. The color shown on the draft is always one ahead of the color displayed on the view window.
