Create a Smart Collection that shows at least 20 pictures in grid view
View - Sort - Label Color
View - Sort - Ascending
None of the cells must be colored
Use the scroll bar to show the 1st. row
Click a cell an press “9” to paint it blue. Repeat this 5 more times to paint non consecutive random cells
Every colored cell must go to the first rows
Now: Click a non blue cell, drag it and drop it on it self
Result: the color order is lost
Note: This situation doesn’t happen if you repeat these steps in a folder, the problem arises just in smart collections
