why the orientation of datatip is not changed using guide in 2014b

It is very strange thing.

I just have made very simple gui using guide. There is just one axes and one pushbutton and one toolbar of data cursor. At the pushbutton callback there is very simple function code such as

ah1=handles.axes1;
x=1:10;
y=sin(x);
plot(ah1,x,y);

after that I put the datatip and try to change the orientation of datatip.

but its not changed.

I tried with lower version 2012a in that case its ok.

I wonder why this happen?
