Hi there, I have just started to optimize Our project I have noticed that the actor account is not changing in in the outliner I have even tried other versions of unreal engine right from version 5.0.3 we are using Version 5.6, I have watched so many tutorials on YouTube and their Actor Count is changing in their Levels, My actor Count in the outliner is not changing but the sub levels are activating and deactivating Correctly, This is a resident evil style game not an open world, the sub levels are activating using blueprint not Always loaded, To load the levels I am using Load stream level by name and the checkbox make visible afterload is checked and to unload the level I am using unload stream level by name, I have also tried using level streaming volumes for the specific rooms and again the actor account is not changing, I will appreciate any help regarding this or if somebody has the time I would appreciate if they could pop into our Discord and possibly help with this issue, Thank you in advance, MAX.

I don’t think the actor count has worked during streaming since 5.
You can see how many there are by pausing ( F8 ) and clicking on the list.
Then F8 to carry on 
Thanks, I have been watching tuts all are unreal 5 they seem to have it working asked questions in there YouTube but they never reply. I will have to try testing this out in old UE4 and also the 5.0.3 anyway thank you for your reply, MAX.
If you mean “Actor Count / Outliner update during PIE” pretty sure in UE4 it was updating in real-time. But somewhere around UE5 rework they changed it? And i think in 5.5 this option was added if that’s what you want? Not sure why it’s not enabled my default. Maybe if you use WP system with a very dense worlds it will cause to much updates for the outliner and performance will suffer? who knows…
This works
