Plones Portal_Setup -> Import steps doesn't work correctly

I have a problem with Plone 4.0.1. At portal_setup, when I 开发者_C百科want to import steps for a selected profile, these steps won't get selected. So for example when I want to run the steps to uninstall a product, the steps do not get selected. So I cannot use any of the profiles for installing/upgrading/uninstalling.

Is there any way to get this fixed again?

Thanks in advance.

Updating Plone to 4.0.9 with some additional upgrade steps to clean up Plone helped resolving this problem, thanks for the help :)
