clarify which related items are returned

when querying items as Administrator, some items include a huge amount of (duplicate) relatedItems. is this just some weirdness with the -development instance, or are related items included regardless their status when querying as administrator?

example, which includes quite a few duplicate relations to "Twitter" and "Gephi":

curl https://sshoc-marketplace-api.acdh-dev.oeaw.ac.at/api/publications/KzRjeN -H "authorization: ${SSHOC_ADMIN_TOKEN}" | jq '.relatedItems[] | [.persistentId,.label]'
