AUTOLAND mode label on 3D trajectory plot

Hi I just loaded an Arduplane bin file from a flight on which I used the new release version Arduplane 4.7
which has an added flight mode called AUTOLAND (ALAND). The 3D plot shows a different colour for this mode
of my flight but the legend/key is not labelled ALAND.

Start at the 3D trajectory plot's flight-mode legend and the mapping that supplies its labels; reproduce the issue with an ArduPlane 4.7 .bin file containing AUTOLAND (ALAND). Done means the distinct trajectory color has an ALAND legend entry.
