Is there a way to change it to a new version?<BR /> <BR /> Kind regards</T></DIV> Fri, 18 Aug 2017 07:53:46 GMT https://community.graphisoft.com/t5/Libraries-objects/Zone-Stamp/m-p/221620#M5328 Anonymous 2017-08-18T07:53:46Z https://community.graphisoft.com/t5/Libraries-objects/Zone-Stamp/m-p/221621#M5329 I don't know what could be causing issue, but what you can try is to go to the Zone Categories Dialog and change the Zone Stamps assigned to each of the Zone Categories from a AC17 Zone Stamp to its AC20 equivalent (provided it is in the loaded libraries).
