Help: setting preferences for a space does not set them...

Hi, I just want to change the copyright notice. We have XWiki 0.9.840. I have Admin rights. This is what I did: 1 create brand new space by linking to it from elsewhere: [Research.Proposals] 2 hit ? to create that page ...view/Research/Proposals 3 Select more actions/Space Preferences/Presentation 4 All fields are shown empty. I assume this is interpreted as "use XWiki preference for this field" 5 I write "Copyright <company name>" in the copyright field 6 Hit Save Preferences 7 Go to page just created and reload. Result: copyright notice still not changed in that space. Am I doing something wrong? I'd appreciate your help --jose
