PQ: 9.5.5

Hello,

In the diary view we have meeting possible to be display - is there any possibility to have them sorted by meeting time ?
Second question - in the diary I see meetings duplicated - when I declare my time for the meeting one instance of the meeting is going to be grayed but second stay. Thery finally (both copies) disapear only when all participants report time. Is it bug or planned functionality ? If it is functionality - how it is working ? Is there possibility to turn it off ?
