Slab required reinforcement

[BenStructural]

Good morning,

I'm trying to analyse a slab in Robot 2013 to calculate the minimum area of reinforcement required. The columns on the project are on a 7.2m grid, and I've modelled these as column supports using the advanced supports setting. When I use the 'slab - required reinforcement' analysis it seems to require tension reinforcement (y-, x-) over the central column as well as the bays on the side. I'm not sure whether I've done something wrong in the analysis or set-up stage but I would not expect this reinforcement over the column to be there. I've attached a couple of snapshots but the file size is too large to attach (11.7MB compressed) can I e-mail this through? I would be grateful if you have any comments. 

Thanks,

Ben
