Am gonna go with the advice I got about going to my local immigration office. If it's wrong it'll just mean going to the border. As stupid as it sounds, it's sounds correct.
I have been advised I need to cancel in the immigration office that first issued it. If I don't the danger of applying for another means it may be rejected. Best to do it properly. Apparently when you cross a border without canceling beforehand, it's not completely canceled apparently. It's such a headache
