How to set current user in « Assigned to » value by default ?

Hello,

When I create an Assignment Object I would like to fill the default value for « Assigned to » with current user. I tried with a rule on metadatacard (set static value = current user), Property Calculator and compliance kit with auto calculated properties but nothing works. 

Please find here screenshot of the configuration : 

Metadata card : 

Another test : Compliance KIT : (I save and Apply the settings)

Another test : Property calculator : 

Version of M-Files Admin : 23.4.12528.8

Please help

Thank’s

Johan
