Could you post screenshots of the scan information that you have set up for this custom patch?
Thanks for the screenshots.
Based on the first screenshot and how it appears that you want this to be a software distribution item I would suggest changing the file detection rule to the "and must exist" option. Otherwise, if you were defining this as an update (patch) you would want to specify a file version for detection.
I hope that helps.
Thank you Adam! It's being picked up now in all my scans.
