In the Event updates screen there is a switch in the upper part to change the View from "Normal" to "Combat only" and "Firing/Damage only".
Neither of these two seems to show anything even though I have just finished a battle where there was both firing and damage, hough my side got only shield damage.
Do these other two views work for you?
EDIT: It worked during combat and now, after it ended, those views don't show anything again.
Do they show only "current interval" range of time or what?
