Missing location data when exporting to Flickr

I am running Yosemite on a new MacBook Pro using the latest version of iPhoto. I noticed that the location data (Places) which I painfully added in to each photo does not translate over when I export to Flickr. Everything else translates with no issues. I use the Share function directly from iPhoto application, not using a 3rd party app. I've use this method of export/sharing for years and location data has not been an issue before.
