Shedule Windows overlap

Hello,

I create a script PowerShell to modify Schedule of Policy, i'm using the command line NBU, bpplschedwin.

The information for the PolicyName / ScheduleLabel  are in a Global Variable, the value for the day is in 2 array, one for the StartTimeJ the other StopTimeJ for the Time during NBU could do some backup. 

Start : 28/04/2020 19:00

StopTime: 29/04/2020 06:00

StopHebdo : 30/04/2020 06:00

    $Global:StartTimeJ = @()
    $Global:StopTimeJ = @()
    $i = 0
    While($i -le 13){
        $Global:StartTimeJ += "0"
        $Global:StopTimeJ += "0"
        $i++
    }
    $NbJourDiff = (New-TimeSpan -start $Global:Start -End $Global:StopHebdo).Days
    $StartTime= ""
    $i = 0
    While($i -le $NbJourDiff){
        $StartTime = (Get-Date $Global:Start).AddDays($i).ToString('dd/MM/yyyy HH:mm')
        $JourStartTime = (Get-Date $StartTime).DayOfWeek
        Switch($JourStartTime){
            Sunday{$Global:StartTimeJ[0] = (New-TimeSpan -Start ($StartTime.Split(" ")[0]) -End $StartTime).TotalSeconds}
            Monday{$Global:StartTimeJ[1] = (New-TimeSpan -Start ($StartTime.Split(" ")[0]) -End $StartTime).TotalSeconds}
            Tuesday{$Global:StartTimeJ[2] = (New-TimeSpan -Start ($StartTime.Split(" ")[0]) -End $StartTime).TotalSeconds}
            Wednesday{$Global:StartTimeJ[3] = (New-TimeSpan -Start ($StartTime.Split(" ")[0]) -End $StartTime).TotalSeconds}
            Thursday{$Global:StartTimeJ[4] = (New-TimeSpan -Start ($StartTime.Split(" ")[0]) -End $StartTime).TotalSeconds}
            Friday{$Global:StartTimeJ[5] = (New-TimeSpan -Start ($StartTime.Split(" ")[0]) -End $StartTime).TotalSeconds}
            Saturday{$Global:StartTimeJ[6] = (New-TimeSpan -Start ($StartTime.Split(" ")[0]) -End $StartTime).TotalSeconds}    
        }
        $StopTime = (Get-Date $Global:Stop).AddDays($i).ToString("dd/MM/yyyy HH:mm")
        $JourStopTime = (Get-Date $StopTime).DayOfWeek
        Switch($JourStopTime){
            Sunday{$Global:StopTimeJ[0] = (New-TimeSpan -Start $StartTime -End $StopTime).TotalSeconds}
            Monday{$Global:StopTimeJ[1] = (New-TimeSpan -Start $StartTime -End $StopTime).TotalSeconds}
            Tuesday{$Global:StopTimeJ[2] = (New-TimeSpan -Start $StartTime -End $StopTime).TotalSeconds}
            Wednesday{$Global:StopTimeJ[3] = (New-TimeSpan -Start $StartTime -End $StopTime).TotalSeconds}
            Thursday{$Global:StopTimeJ[4] = (New-TimeSpan -Start $StartTime -End $StopTime).TotalSeconds}
            Friday{$Global:StopTimeJ[5] = (New-TimeSpan -Start $StartTime -End $StopTime).TotalSeconds}
            Saturday{$Global:StopTimeJ[6] = (New-TimeSpan -Start $StartTime -End $StopTime).TotalSeconds}    
        }
        $i++
    }
}

}

When i just done a Write-Host of all value:

PolicyName: RGS_MGMT_P
Label: Incr
Tableau StartTimeJ: 0 0 68400 68400 68400 0 0 0 0 0 0 0 0 0
Tableau StopTimeJ: 0 0 0 39600 39600 39600 0 0 0 0 0 0 0 0

All the Value is good ! but i have this error :
.\bpplschedwin.exe : schedule windows overlap
Au caractère C:\Admin\NBUv5-EnCours.ps1:281 : 5
+ .\bpplschedwin.exe $Global:PolicyName $Global:ScheduleLabel -0 $G ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (schedule windows overlap:String) [], RemoteException
+ FullyQualifiedErrorId : NativeCommandError

When i done the same command line to a Full Schedule, the result of the command line is OK !

Do you know the meaning of this error and how to resolve it ?

Thx a lot for you'r help ;)
