my aperture options won't change over besides the house icon, tried taking a shot of my friends outdoors and it came out black. Even though I rotated the lens onto the sunny icon (indicating outdoors) wondering how I can fix this? Would really appreciate it. Indoors is fine and so is everything else just can't seem to change the aperture options?

Just got a mini 8 one of these, and everythings good besides the aperture feature is a bit iffy. The light doesn't indicate and change onto the mode i rotate the lens onto. It works for the house icon, but doesn't change to the other options. Wondering how I fix this? thanks :)
