I'm not new to CUIC (12.5 UCCE) but this has me stumped. I have Call Type report that shows zero calls in the "Assigned From Queue", zero "Max Queued", but shows data within the "Longest Queued" column. See attached sample report.
Also, why is the SL% shown in the summary bar if it's incorrect?
If you export the SQL query and run it on the HDS itself, do you see the same data (just to rule out some type of formatting issue).
If it were me, I would pick one time period and look at one interval and look at the call and see what you see if you look at the call detail. Is it possible the scripting does something odd like dequeing the call or overflowing someplace else?
