[Q] PA Notification LED Bug topic

I've been using PA ROM for Galaxy S3 i9300 for a while now. So far didn't have any major problem except rare auto-restarts. But now I'm facing an issue with LED notifications. While the screen is off for any new notifications at the time of arrival the LED flashes once and that's it, then no pulsing. The notification settings are intact. What could be the problem?

Device GT-i9300
ROM: PA 4.45 for S3 STABLE
