Look at the “scans have been executed” chart (top-left).
I see a strange picture when the number of my scans (blue bar) more than average (gray bar).
Look at the attached image (not screenshot) and real screenshot.
Because I did some testing with custom scans, I have now 11 scans and the blue bar is here shorter than the grey bar too. Indeed a small gui bug, nothing serious
