Hi Julien,

I tried to reproduce the behaviour (forcing the parsing of the contact 
header somewhere in advanced), but, still, I got the right value.

Maybe the issue is somehow specific to your configuration (which I 
cannot reproduce).

Is somehow possible to get access on your machine and to try to 
troubleshoot it??

Regards,
Bogdan
