[xwiki-users] Permission problems after XAR import

Hi, I've recently updated my Xwiki using the same process as always, however some Administration pages are showing the following error at the bottom now. --- Customize XWiki.RegistrationConfig: This configuration cannot be displayed because it was last edited by Admin who doesn't have permission to edit this page. --- --- Annotations Customize AnnotationCode.AnnotationConfig: This configuration cannot be displayed because it was last edited by Admin who doesn't have permission to edit this page. --- There is no user Admin, so i'm not sure where it's getting this from. My account is the only Admin in the wiki. Is the import process somehow trying to use "Admin" ? Thanks.
