port offset does not work

steps: 1. install a local EAP v7.1.0 binary 2. On Studio, create a new server, create a new runtime environment to point to the server root folder. 3. double click the server to see the overview page. 4. On the port offset under server ports, define a custom offset like 100, see attached 5. Note that the standalone.xml keeps default, so jboss.socket.binding.port-offset is 0 6. start the server expected result: since I manually define a port offset, the server should start with the port, as the web console port as 8180, management port 10090 actual result: the server is still started with default port-offset (0) below log: 11:28:07,130 INFO [org.jboss.as] (Controller Boot Thread) WFLYSRV0060: Http management interface listening on http://127.0.0.1:9990/management 11:28:07,130 INFO [org.jboss.as] (Controller Boot Thread) WFLYSRV0051: Admin console listening on http://127.0.0.1:9990 11:28:07,130 INFO [org.jboss.as] (Controller Boot Thread) WFLYSRV0025: JBoss EAP 7.1.0.GA (WildFly Core 3.0.10.Final-redhat-1) started in 7005ms - Started 430 of 656 services (353 services are lazy, passive or on-demand)
