Put out fire in a neighbors oven social task

I have completed the social task: put out fire in a neighbors oven 3 different times.  Every time the oven caught fire and I put the fire out in my neighbors house.  But the task will not go away.  It does not show completed and I can't move on.  I have tried several different ways, always completed it at the neighbors house.  I have searched on the internet.  The only thing I can think of is that I can only use brownies.  I have used other baked goods with the flames but I don't have access to the brownies yet.  only on level 11.  Any ideas?
