Retry failed test cases fail in test suite - All retrying tests couldn't pass authorization

Run test suit with the following parameters :
_ OS Windows 8.1 64bit_
_ Katalon version:
_ Browser: Chrome 68.0.3440.106_

katalon -noSplash  -runMode=console -consoleLog -noExit -projectPath="C:\pr.prj" -retry=1 -retryFailedTestCases=true -testSuitePath="Test Suites/All ready test staging" -executionProfile="QA" -browserType="Chrome"

I got some failed tests. Katalon create new run with this failed test but all of them failed with error:

FAILED Unable to navigate to authenticated page (Root cause: java.lang.IllegalArgumentException: Password is null)

Does anyone know what is the reason ? Why tests pass authorization from the first run and fail on this step during repeating run.Please, share a decision if you know.

Authorization part of test: using Global variables
