WordPress MU

Last time i added a few blogs, there is a problem mit the editor-rights of these blogs.

In my new blogs the editors haven´t rights to change themes an the whole menu "design" isn´t there.

In my old blogs (i think i added them with the previous version of mu), there is no problem and all editors can change the themes.

I found, the problem is the content of the table wp_XX_user_roles. XX is the number of the blog.

Now i copy the content of this table from an old blog to the new ones and it works fine.

But how can i fix this problem ?

That's strange as Editors shouldn't have those rights, normally it;s only admins.
