No way to remove linked package from a project series page

Although it is possible to remove a linked package from the distribution package page (e.g. https://launchpad.net/ubuntu/+source/creox), it is not possible to do so from the project series page where that linked package appears (e.g. https://translations.launchpad.net/ubuntu-doc/+packages). It should be possible to remove the link from both places (I saw an erroneous link on the latter page but had no idea that I could delete it myself from the former page - see https://answers.launchpad.net/launchpad/+question/26017).
