Some months seem to be missing from the reports.
When looking at your Income and Expense By Month graph, or your Profit & Loss - 12 Month Comparison reports, you might be inclined to ask, "Where are certain months? For instance, this report shows me March 2014 - Feb 2015, so what happened to Jan and Feb 2014"?
These two reports are only displaying the previous 12 months. They are meant to help you spot useful trends. It doesn't mean that any months are missing from your reports, we simply can't fit more than 12 months on the page without it getting very small.
But your Profit & Loss - Yearly Comparison report is on the next page, and it includes all months for those years displayed. And your Transaction Detail link in your Dashboard will also display all your transactions for the last few years.
