PhD in France

Hi I have a question about applying for a PhD in France. I know that I can contact professors directly or find already published offers on campusfrance. I just applied for one there and the prof replied that this is not a doctoral offer but a grant application (it is clearly listed as a PhD position) and directed me to apply for funding with my own proposal, which was very confusing. I also found that adum.fr has a tonne of proposals some of which I've seen on campusfrance too. Are these also active and funded offers or not? In short there are a thousand websites with conflicting info and if someone could help me I am buying dinner once I get in! Merci bcp :)
