Try specifying the parent axes in advance with axes():

axes(handles.layoutAxes);
rectangle('Position', [X_coordinate(i), Y_coordinate(i), 2, hdend(n, 1)]);

It appears that the syntax that you use is not supported by the rectangle documentation. The online documentation lists these syntax variations:

rectangle
rectangle('Position',[x,y,w,h])
rectangle('Curvature',[x,y])
rectangle('PropertyName',propertyvalue,...)
h = rectangle(...)

but your code is something like this:

rectangle(h,'Position',[...])

You should read the rectangle properties documentation, particularly the section entitled 'Parent'.
