Hello

I have just fixed this issue, by removing the aliases from the datapusher
as this causes issues on duplicate resource names (as Joe mentioned)

You will need to refetch the latest datapusher data and restart apache.
cd /usr/lib/ckan/default/src/datapusher
git pull
sudo service apache2 restart

Thanks

David
