created vs. resolved gadget shows incorrect resolved total

Hello,
I have a created vs. resolved gadget on my dashboard and I've noticed that the number of resolved issues is incorrect in the chart.

Here are the steps to reproduce:
1. create a dashboard
2. add the created vs resolved gadget to the dashboard (can be for all issues in a project or using a filter - doesn't matter); and can be for any number of days
3. take note of the number of resolved issues
4. now run a manual query and compare the number of issues that are displayed (so for example if your chart is pulling the data for the last 30 days >> project = ZZZ AND resolutiondate >= -30d)

Result: the number of resolved issues shown in the chart does not match the number of resolved issues in the search view

Expected result: matching numbers
