Okay thought about this a bit more.
change the problem notification to use {TASK(Active,Result.UploadedFilesNames)}
on the test job {TASK(Active,Result.UploadedFilesNames)} and {TRIGGER(Active|LastTrigger|File.Result.Name)} produce the same result, only one file is loaded to the folder, so that works okay.
I'll update this post when the live data is uploaded to the server that was having the issue.
