From context it looks like 'A030' is 3000 feet MSL. Is that an FMS format or something?
In recent years we've had a rash of incidents where the arrival was 'cleaned up in the box' and altitude constraints were inadvertently deleted from the vertical navigation path.

The operational incident is being investigated, with an expected completion of July 2017.
Good thing it's nothing important, so no hurry, right?
