Top footer – Instagram widget not showing chosen number of pictures!

Hi again.
I’m using Instagram widget in Top Footer (great feature btw), but I can’t make it work properly.
I have chosen to show 16 pictures in large size from an account @leboucherdantan, but it’s showing only 12, no matter what I do…..
The concern website is:

Could you please tell me how to fix it?

Thanks again for a great Theme !!!
