Hi all, What is the correct process to undo merges? There are three cases where a bibliographical article (in Wikisource) has been accidentally merged with the human the article is about: http://www.wikidata.org/entity/Q85393 http://www.wikidata.org/entity/Q312607 http://www.wikidata.org/entity/Q320923 The merge in each case should be undone, and the "main subject" property be set instead, like here: https://www.wikidata.org/wiki/Q15985561 But the "undo" option in the history just deletes the merged-in statements (it seems) without restoring the old page. What to do? Markus
