The reason is probably that you need to find the challenges manually by exploring the roads.

Actually, I had something similar happen to me, long after I completed the 'discover all roads' acheivement. I was missing 4 hitchhiker missions which did not show up when I used the filters to show only those types of missions. Once I noticed that I never got the acheivement for completing what I thought was every race and every challenge, I had to go back and turn off filters to view all races, before I could find the 4 missing hitchhiker missions. I just figured that out last week and got the all races and all missions acheivement, even thought I thought I had finished them 2 months ago.
