Why only 8 episodes?

When it was shown on Watch I think one of the series was cut down for breaks I think most of the series it went longer than the hour slot to allow for breaks but I think it was when they showed series 5 is was cut down because I remember the ep at the Africa conference they cut out H/R meeting in corridor.. at least I think it was that, something like that..
