The default for the preset dashboard tiles like Income Last 6 Months, Expenses Last 6 Months, is to include the current month. This suits those who want to see month to date progress but not everyone.
Follow these directions to customise your own variation on the dashboards, for additional information see Dashboards: Change Tile Date Ranges
