Sessioncreator CLI never returns ERRORLEVEL 1

EDIT: I tried the same using TestExecute instead of SessionCreator, TE does return the Errorlevel 1 warnings. SessionCreator does not.

For me I only get back ERRORLEVEL 0 on warnings, I did use SessionCreator not Testexecute.

"C:\Program Files (x86)\SmartBear\TestExecute 15\x64\Bin\SessionCreator.exe" RunTest /Username: /Password: /ProjectPath:"PathTo\TestErrorLevel.pjs" /UA /ScreenResolution:1600*900 /Timeout:9000 /project:TestErrorLevel

IF ERRORLEVEL 1001 GOTO NotEnoughDiskSpace
IF ERRORLEVEL 1000 GOTO AnotherInstance
IF ERRORLEVEL 127 GOTO DamagedInstall
IF ERRORLEVEL 4 GOTO Timeout
IF ERRORLEVEL 3 GOTO CannotRun
IF ERRORLEVEL 2 GOTO Errors
IF ERRORLEVEL 1 GOTO Warnings
IF ERRORLEVEL 0 GOTO Success
IF ERRORLEVEL -1 GOTO LicenseFailed

:Timeout
GOTO End

:CannotRun
GOTO End

:Errors
GOTO End

:Warnings
GOTO End

:Success
GOTO End

:End
echo %ERRORLEVEL%
pause

In the TestErrorLevel project there is this test:

function test1()
{
  Log.Warning("This is a warning");
}

The test was run through the Execution plan
