**Steps to replicate the issue** (include links if applicable): * An editor participate to an ISA campaign * He changes the rank of a claim from Normal to Preferred **What happens?**: * The claim had a qualifier (color: green) * on Commons, the rank is changed from Normal to Preferred (ok) and the color property is removed. ---> Information loss * editors revert the edit from ISA. If done repeatedly, the ISA editor is considered a vandal **What should have happened instead?**: * on ISA, qualifiers are not proposed. Either they should be added to the tool, or the change of rank of a claim should not be removing a claim qualifier Also noted with qualifier Background Examples : * https://commons.wikimedia.org/w/index.php?title=File:Crique_de_l%27Anau,_Sète,_Hérault_01.jpg&type=revision&diff=683493430&oldid=622081503&diffmode=source * https://commons.wikimedia.org/w/index.php?title=File:Building_of_the_Salins_de_Frontignan_01.jpg&action=history * https://commons.wikimedia.org/w/index.php?title=File:Black-headed_weaver_(Ploceus_cucullatus_bohndorffi)_male_nest_building.jpg&type=revision&diff=683495599&oldid=675021045&diffmode=source
