I made a GUI and I put this:
% --- Executes just before kkkkkkkk is made visible.
function kkkkkkkk_OpeningFcn(hObject, eventdata, handles, varargin)
% This function has no output args, see OutputFcn.
% hObject handle to figure
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
% varargin command line arguments to kkkkkkkk (see VARARGIN)
%Ao carregar o programa sem fecha-lo, aparece vários menus oi
% Choose default command line output for kkkkkkkk
handles.output = hObject;
ff = findobj(handles.output, 'tag', 'k')
j=0;
for x=1:3
j(x,1)= uimenu(ff, 'tag', strcat('t',num2str(x)), 'Label',num2str(x) ,'Callback',@jj_Callback);
end
% Update handles structure
guidata(hObject, handles);
Without to close that figure, I rerun it, so, when i do that, the menus reshow.
See: I run once, it shows 3 menus items. When I rerun, it shows 6 menus: 1,2,3,1,2,3; and that follow. So, if I rerun that program without close it 6 times, it shows 1,2,3,1,2,3,1,2,3,1,2,3,1,2,3,1,2,3,1,2,3.

You are not clearing out any existing children when you start the function.
You could force everything to be reset by deleting the figure when you are done with one run of it.
