This may be more of a bug report but ever since upgrading to the latest 5.7 when I'm editing one of my generic scoreboard widgets I cannot rearrange the selected metrics. It seems to at random just re-arrange them when I edit the selected metrics.
Takes twice as long to do anything because I find that I have to add everything one by one to get them in the order that I would like.
Bummer to see this kind of regressions in a point release of a product.
