routing wrong in new editor and settings

our IT has installed zanata as zanata.mycompany.com/zanata

in settings page the links/routes are now pointing to zanata.mycompany.com/link.. and not to zanata.mycompany.com/zanata/link..

the same is true for the new editor. i can open a file for translation in the new editor, but when i want to switch it it results in 404, cause /zanata is missing in the Uri
