Singapore appearing in wrong UK postal Zone

[Anniemcc2]

Noticed yesterday when doing my p&p editing before new UK postal rates come into effect tomorrow, that Singapore comes up in Zone 1 when Asia is ticked - it should be in Zone 2 with Oceania.

Royal Mail's list of which countries are in which zones:

Singapore is NOT in Asia [according to RM] but gets a tick when Asia [Hong Kong, India & Malaysia] is ticked when listing. Trust that makes sense !
