The LR Flickr publish service in CC 2015.2.1 / OS X 10.10.5 is causing Flickr to handle improperly multi-word keywords.
For example, if you publish a photo with the keywords "Peter Ellis" and "Lake Powell", Flickr will show four keywords attached to the photo: "Peter Ellis", "Peter", "Ellis", "Lake Powell", "Lake", "Powell". This is incorrect.
However, these methods do not exhibit the incorrect behavior:
- Publishing to Flickr with CC 2015.1.1 and the LR Flickr publish service. - Publishing to Flickr with CC 2015.2.1 and the Friedl Flickr publish service. - Exporting to the desktop from CC 2015.2.1 and then uploading to Flickr via the Web browser.
All these methods result in Flickr showing just the keywords "Peter Ellis" and "Lake Powell". Thus, the bug is specific to the Flickr plugin in CC 2015.2.1.
In all cases the export settings were the default plus these: Include All Metadata, Remove Person info unchecked, Remove Location Info unchecked, Write Keywords As Lightroom Hierarchy checked.
