Your checking for filters sounds right.
Are you perhaps filtering by a pointmap being zoomed in, it is the only filter that would not show up as a filter on the dashboard icon.
If it is not a pointmap filter, I would recommend you take a look at the query being sent from Immerse to MapD Core to review what it is filtering on. The queries are visible in
mapd_server.INFO in the /data/mapd_log directory.
If you don’t want to look through the logs another approach is to delete the charts on your dashboard one at a time and see when your count returns to the expected count value.
There has also been a bug with filters on time charts not clearing correctly (this is normally visible on the chart itself though) but it is fixed in v3.2.2, i would recommend you make sure you are running 3.2.2 if you haven’t already updated.
