Execute not appearing on timeline > casts

Looking through the logs, execute does not show up being tracked when looking at timelines > casts, it’s just a long blank area until the boss dies. Execute damage is being tracked in the tables > damage done tab but you can’t see them in casts for some reason. Curious what would cause this?

If Blizzard didn’t properly fire a cast event for it…

Yeah execute is very buggy in general atm. It has a 800ms delay before the damage is dealt, a lot of people are losing a ton of damage casting it near boss death rofl.
