Sometime today I've noticed my notifications not clearing after viewing them. I have to manually hit the mark all as read to clear them. 

Not sure if just me or a bug

*edit I should say events not notifications

Can confirm this is an issue no matter how times you view the event log.

Only way I've found to clear it is to click the 'Set all to read' button on the event logs page.

The same thing happens for me. Every new event requires me to click "set all to read".
