Managed Challenge

I created a challenge for visitors from a country under Firewall Rules. When checking the statistics under Firewall Rules is see 0 % as the number of visitors that managed the challenge.
However, when going to the Firewalll Overview tab, I noticed many instanced of so-called ‘Managed Challenge’. What could be the reason for this discrepancy ? The country I am ‘challenging’ has a lot of visitors that try to download content from my site. Maybe they are using some ‘trick’.
