Facebook Organic Reach. I only get data from the last 6 months

Hi all,

I´m trying to get the Organic Reach data from a Facebook account and I only get results from the last six months, and I need the data from the last year. I get without problems the data from viral and paid reach, but only six months from organic reach.

Any idea? Is this a bug of Supermetrics or a restriction from Facebok Insights API?
