The job can be expanded as long as it has at least one dependant task, right? If you expand it, you should be able to see one active and the other disabled.
Something similar happens when a dependent task fails: the parent task appears as "Failed" even if it didn't.
However, I don't know if this is a WAD or a bug, anyway I think it's worth checking with firstname.lastname@example.org.
Hope that makes sense.
