Yard mode doesn't work on encoder throttles if the "Radio Fix" is turned on in the command station setup menu. "Radio Fix" was an attempt to fix a radio bug prior to the RB02. The bug was fixed with the version 2.0 firmware. If you have a new (or upgraded) RB02 ( version 2.0 or greater) then you should turn the Radio Fix off as it is not needed. With the Radio Fix off yard mode works fine with all throttles, both pot and encoder types.
