Weapons >> Clearing a double feed in Benelli Suprnova?

I am new to shotguns and have been to the range a few times with this gun and I do love it. But, last week I got a double feed (no doubt a short stroke) and had to get the range officer to clear it for me. I felt like a tard.

How do you clear a double feed on Benelli supernova. It seems to be a bit different from Mossbergs and remingtons and there are no internet vids (at least I could not find any).

Thanks for any help.
