There were several fixes for templates in productized application-templates - but these were not propagated to dev version (so it would happen again in productizing phase). See eg. https://github.com/jboss-fuse/application-templates/blob/application-templates-2.1.fuse-730002/fis-image-streams.json#L569 vs https://github.com/jboss-fuse/application-templates/blob/application-templates-2.1.fuse-720018-redhat-00001/fis-image-streams.json#L575.
