Possible Bug in Rule Machine

I have found when using 'color by mode' that if you set the colour for a mode to one of the whites and then the level to 0 to signify it is turned off, when you go back in and change the level to something other than 0 it always resets to zero.

Similarly if you set it to 'pick a color' and then change it to one of the whites if shows the level that the colour would have been, which I would have expected, but it doesn't allow that to then be changed.

Both situations still exist if I finish my editing and then go back in.

Is this something I am doing or a defect?

after I posted this I found I had an excessive load and when I rebooted my HE hub to resolve that it also resolved this.
