In addition, I think you've put a "6" next to JNB because this destination is priced as a zone 6 even though it's physically located in zone 7.
The same also applies to CPT - indeed, as it's even further away from London it arguably merits a flashing green dot, not that it needs it at any time of the year when people normally think about redeeming to CPT.
