Lead qualification process

Hi,

I just realized that when you qualify a Lead, it creates an opportunity, an account and a contact. The "contact" field at opportunity entity isn't getting filled also my custom field "country" (I guess I should do something here) is blank.

After I qualify a Lead, the account created is getting linked in the opportunity entity, why the contact isn't ? it is made that way or is something wrong with my configuration?

Also, my custom field is a custom entity, how can I make the qualification process link my lead's country to all three entities?

Thanks for reading/helping :)
