You have not provided anywhere near enough information to receive assistance. I suggest that you navigate to the content that is not fully visible using the Repository view in Share. Then you can look at the full set of permissions and see if that sheds any light on the situation. If it does not, copy and paste the permissions into a reply along with your specific Alfresco version and any error messages you might be seeing in the log and maybe someone will be able to help you troubleshoot.
