Hello--Currently we have around 32 open defects (submitted state, open state, and re-open state). We would like to use the report "Defect Trend," however, it appears that it is including the defect state "Not a defect" as part of the graph (29+1+1+19=50 defects).
I believe someone asked a similar question about this report in 2016 and there was no response. I asked my system admin to fix this/look into it, and their only response was to contact the developer for this app to update the source code.
