How do I stop Calendar overriding my Event location

Hi

When creating an event in Calendar, the software is quite 'helpful' in offering suggestions for the event location as I type.

However, if I don't like any of it's suggestions, or wish to override the suggested location, the software seems to stamp it's feet and insist on formatting the location data the way IT prefers.

How do I stop it doing that?

For instance, I am attending an event at the "Institute of Directors, 116 Pall Mall, London, SW1Y 5EA"

Calendar finds a very close match for this and replaces my location with

"116 Pall Mall

London

England

SW1Y 5EA

United Kingdom"

Apart from the excessive screen real estate taken up by those superfluous new lines, it doesn't include the name of the location - "Institute of Directors" - and it includes 2 countries - England and United Kingdom - that I don't need to know because I live here.

Can I not keep my own preferred format in the location field?
