RQM test case always shows Pass, even when test script returns non-0 value

I have an RQM test case that calls a command line test script (Windows batch file) via the RQM Command Line Adapter. My test script returns 0 if successful or 1 if failed, however when I run the RQM test case it always shows Passed, even when the test script returns 1.

To debug it I've modified my test script, CLI_Run_Jenkins_Job.bat, so it just returns 1. If I call this script from another test script, test.bat, that checks its result, it does return 1, so test.bat proves that CLI_Run_Jenkins_Job.bat is working as expected. However when I run CLI_Run_Jenkins_Job.bat from an RQM test case via the Command Line Adapter the RQM test result always says Passed.

Do I need to do anything special with the Command Line Adapter to make it return the result of CLI_Run_Jenkins_Job.bat? If not, is there anything else I need to do?

I'm using RQM 4.0.1 with RQM-Extras-CommandLineAdapter-4.0.1.

The batch files are:
CLI_Run_Jenkins_Job.bat:
    exit /b 1

test.bat:
    echo START
    set errorlevel = 0
    call CLI_Run_Jenkins_Job.bat Checkout_TCISDemo_Source
    if errorlevel 1 goto error
    echo PASSED
   
    :error
         echo FAILED
