[OBD U5] mismatch alert when using command line

Hi,

Using cmd string below as a test. The attached dgn file is located in C:\ProgramData\Bentley\OpenBuildings CONNECT Edition\Configuration\Datasets\ 

"C:\Program Files\Bentley\OpenBuildings CONNECT Edition\OpenBuildingsDesigner\OpenBuildingsDesigner.exe" -wkexample -wwmetrostation "C:\ProgramData\Bentley\OpenBuildings CONNECT Edition\Configuration\Datasets\test_nowsww.dgn"

Expected result would be no mismatch dialog displayed, seeing the Datasets folder is included in MS_WORKSETMISMATCH_ALERT_EXCLUDE_VARS_ALLLEVELS by default. However, the mismatch alert box still shows up. 

If I click cancel and open the the same file from backstage, OBD will open the file without any hassle, no mismatch alert.

So how do I open straight into a dgn that doesn't have the right workset assigned in OBD U5 without the mismatch alert?
