If "Emergingthreats.net Community Rules" is selected, detections are displayed without issue. But, if "Abuse.ch SSLBL Blacklist Rules", "Travis Green - Hunting rules" and "Etnetera Aggressive Blacklist Rules" are selected, the number of detections is displayed in the "IPS Logs" but no summary of them. If the file "fast.log" is analyzed, all the detections appear but not in the GUI. https://community.ipfire.org/t/intrusion-prevention-system-issue-after-update-to-core-168/8093
