Can you please advise what the issue might be here, is this something we are doing incorrectly?

Sorry about that, we are taking a look now at issue

This indicator has been in the schema for many years but was never implemented it was a last minute change in policy decision. Customer care notified developers at the time not to use it. Unfortunately we didnt remove with the latest version, however we are going to have a new version of this schema in the upcoming months to enable the PSC & members historical register to be added and we will take this opportunity to remove it as its very confusing. Sorry for confusion caused.
