Several groups with one consecutive color after filtering

[Callistemon]

When the quick filter is used in Version 5 to only show groups with 2 items, there are often multiple consecutive groups that are all the same color and appear to be the same group. It does not realign the alternating group colors after a filter is applied, so it is easy to select almost all files in those groups without checking the group number. If the user ignores the warning that some groups have all files marked because they intentionally selected all files in other unrelated groups and assumed those were the only groups that had all copies checked, all copies in these consecutive groups could be deleted.

Will fix

This issue does not occur when dropping items permanently (until scanned again) from the list, only when temporarily filtering. Thanks for fixing this.
