Deleting an organization is not working

When I try to deleting an Organization as a sysadmin, choose Organizations from the side menu, click on an Organization's name, click on Delete. Nothing happens, the organization is still there. In the log: I, [2019-06-06T14:47:34.095584 #12961] INFO -- : [a6411661-97d5-4561-aad7-d0c009bd2bdb] Started DELETE "/system/organizations/2" for 81.119.165.43 at 2019-06-06 14:47:34 +0200 F, [2019-06-06T14:47:34.107050 #12961] FATAL -- : [a6411661-97d5-4561-aad7-d0c009bd2bdb] F, [2019-06-06T14:47:34.107143 #12961] FATAL -- : [a6411661-97d5-4561-aad7-d0c009bd2bdb] ActionController::RoutingError (No route matches [DELETE] "/system/organizations/2"): Thanks, Gian Luca
