1) Editable UIControl property need to be empty string i.e delete string(default string is Edit Text) and put the empty string when you place editable UI control onto GUI layout
or
2) In your GUI opening function <filename>_OpeningFcn(hObject, eventdata, handles, varargin) write the statement as
handles.<your_edit_UI_control_tag>.String = '';
