Hello AussieDebs,

Thank you for using Apple Support Communities!

We understand from your post that when adding your current location your old location is added instead. Make sure that you have Location Services enabled for Calendars as described in this article:

Best Regards.

If necessary you can click the link that says "Get Support" in the upper right corner of this page to speak with Apple Support. We're users like you and can't tell you why this is happening. We can only guess about how to fix it.
