FAVORITES: multiple appearance of same icon;
You try to correct it, an other double icon appears!

furthermore, MARK/UNMARK as FAV shows the wrong option for already SETTLED/UNSETTLED icons.

Especially happens when scrolling trackpad laterally directly from ALL to FAV, for instance.

REBOOT often makes things worse.
All main icons arrangement is lost, and also often my email accounts don´t appear nowhere, or only one of them appears.

SHOW ALL at full menu, leads to similar undesirable effects.
HIDE: hiding an icon results in a very difficult way to retrieve it.
