I have logged a bunch of challenges, but not all do have a checker result on the "Challenges" tab, i.e. there is neither a green nor a red button on the right. Instead, there is no result shown at all. Manually running the checker, which IS linked on the cache page, does get a proper result.
I have tried updating one/all caches using the Self Service, but apparently that doesn't have an influence on the Challenges list.
So, how do I ask one/all checkers to be re-run and updated in the Challenges tab?
