I just found a fix for the exact same issue. When your shutter extends out, before it goes back in turn the largest grey base piece that is the bottom largest of the three rings in a clock wise direction with a little torque. It worked perfect for me, you have to do it every time, but it works like a charm. Be sure to do it when its fully extended, you should have a 1 in 3 chance before you have to turn it off and turn it back on again and try it. Try it out! It might work for you.
