Primary Contact Details not automatically updated in Project

Hi Guys,
I just noted, that when I correct ie the email address from a Contact and this contact is Primary Contact for a Project it doesn't automatically correct the email address in the Project table. I have to manually go to the Project and correct it again. That doesn't make any sense.
How can I change it so it automatically updates emails and phone numbers?
Thanking you in advance.
Kind regards
Regine
