copyobj from GUI to new figure but after closing figure GUI obj disappears

So I have a gui that reads some data and plots it on an axis figure on the GUI itself.

The GUI also has a "export graph" button, which uses copyobj and copies the axes, and legends onto a new figure.

Everything works except when I call the command to close the figure. This command closes the figure, but at the same time, some of the objects from the original GUI disappears with it, namely the legend, and the secondary axis.

Anyone run into this issue before?

Are you specifically copyobj()'ing the legend? legends reside in their own axes.

Can you test to see whether after the legend has been copied, whether the annotation objects of the original and the copy are the same object (not just same string)? If so then a delete() of the original might affect the copy.
