Still having issues with Date switches changing to US Format, I have had all regional settings checked against the data source system , the host server and local machine all set to UK.

Each time I use a date switch this converts my date to a us format , I have tried using the following switches but each one keeps converting to a US Date format.
MERGEFIELD DOB\@ "d"\*ordinal MERGEFIELD EBZ101\@ "MMMM yyyy"
MERGEFIELD DOB\@ "d"\*ordinal MERGEFIELD EBZ101\@ "MMMM yyyy
MERGEFIELD DOB \@ "d MMM yyyy"
MERGEFIELD EBZ101\@ "d MMM yyyy"

When I leave the field with out any switches the data is kept in UK Format of DD/MM/YY

Any suggestions would be gratefully received
