Missing defaults for function arguments

Hello guys.
I want to report serious bug in pgAdmin 1.14.3.
SQL pane, as well as create script for functions shows no defaults for
function arguments. Doesn't matter if it is DEFAULT NULL nor some other
datatype
On the other hand function properties window shows defaults as expected.

v1.14.0 shows everything correctly

example:

instead of
CREATE OR REPLACE FUNCTION some_function(arg1 character varying, arg2
integer DEFAULT NULL)
v1.14.3 gives:
CREATE OR REPLACE FUNCTION some_function(arg1 character varying, arg2
integer)
