Alert Storage 7.7.2 rc1

Hello.
In manual
support.inductiveautomation.com … wledge.htm
in first row we can see about Alert Storage and configuring of this. When we pressed “Alert Storage” we go to support.inductiveautomation.com … torage.htm
where we can find information about Alarm Journal but nothing about Alert Storage.
Where i can find any info or configuring of Alert Storage like in Ignition 7.6 ?
I need it for system.alert.queryAlertHistory(storageProfile)

So, i found the same problem here
viewtopic.php?f=70&t=10776&p=38223&hilit=alert+storage#p38223

But, using

system.alarm.queryJournal(journalName="Journal",state=['ClearUnacked', 'ClearAcked', 'ActiveUnacked', 'ActiveAcked'])

i can see only the list of “ClearUnacked”, “ActiveUnacked”, “ActiveAcked” but can not see “ClearAcked” alarms. When i ack the “ClearUnacked” alarm it goes to “ClearAcked” and makes invisible(deleted). But i want to see all the list of alarms events look like the alert_log in Ignition 7.6
