Position() has been phased out so that only Legend Position() is output in saved scripts. Previously saved scripts that include both the Position() and Legend Position() commands generate an error even though the script runs fine.
For example, change the following code:
{Legend Position( {3, [-4, -1], 5, [0, 1, 2]} ),
Position( {-4, -1, 0, 1, 2} )}
It should read as follows to avoid the error:
{Legend Position( {3, [-4, -1], 5, [0, 1, 2]} ),
Legend Position( {-4, -1, 0, 1, 2} )}
