Content picker always shows English content folder, not the subsite content

See attached screenshots.
The first one shows the English content tree. Note the folders under News: 2010, 2009, 2008, 2007, 2006, 2005, 2011.
The second screenshot shows the Dutch content tree. The folders under news are called: 2010, 2008
The third screenshot shows the "Content path" field in the HST Config Editor for the Dutch site ("Ga Groen").
Now I click on the [...] which opens up the picker - shown in screenshot number 4.
The picker now shows the English News folder, as you can tell from the subfolders: 2010, 2009, 2008, 2007, 2006, 2005, 2011.

This is very awkward because it means you can't change any of the Content paths in any one of the sites other than the English website.
It's rendering the multi-channel features of Gogreen almost completely unusable.
