JEA not active after first "Install-IcingaSecurity"-command

I tried to activate JEA by executing "Install-IcingaSecurity" in an admin-PS:

PS C:\> Install-IcingaSecurity

As a result all services switched to "Unknown" with the following plugin-output:
Icinga Exception: Unable to start the PowerShell.exe with the provided JEA profile "IcingaForWindows" for CheckCommand: <check-command>

After executing the command a second time, the JEA-settings were set correctly and all checks are running fine:

PS C:\> Install-IcingaSecurity

However show-icinga doesn't show the user for the "icinga2"-service correctly:

Icinga for Windows environment:
-----------


Environment configuration:

PowerShell Root                 => C:\Program Files\WindowsPowerShell\Modules\
Icinga for Windows Service Path => C:\Program Files\icinga-framework-service\
Icinga for Windows Service User => .\icinga
Icinga for Windows Service Pid  => 2464
Icinga for Windows JEA Pid      => 6112
Icinga Agent Path               => C:\Program Files\ICINGA2\
Icinga Agent User               => icinga
Defined Default User            => DEHWLWOPSMGRT11\icinga
Icinga Managed User             => True

=> I would expect ".\icinga2" for "Icinga Agent User" like the "Icinga for Windows Service User".

But it was correctly set:

Start by reproducing Install-IcingaSecurity on Windows and compare the first and second executions, including the icinga2 and icingapowershell service identities. Check the output of show-icinga and the JEA startup failure; done means the first execution activates JEA successfully and reports the expected agent user.
