Manage Resources: Not able to save some values

After changing a value in the "Manage Resources" section of the venture theme the new value is not saved but reverted to the old one. This ONLY happens when German is selected - it works perfect in english.
Example for the filed: sevenspikes.themes.venture.common.address
Values not being part of "sevenspikes.themes.*" seem to work as well.
Thanks for any ideas!
