is this actor genuinely foliage? because i can individually select them

Hello!
So I have three types of foliage: trees, buildings and a body animation (I created a NewActorFoliage and added a Blueprint Actor with a .abc animation file from Blender inside of it).

When I exit foliage mode and click on buildings or trees, they all get selected collectively:

But when I click on these animated bodies, they are selected individually even though I placed them as foliage:

Does that mean they aren’t really foliage and will take performance hits individually?

If that’s the case, can you suggest me a cost efficient way to have a lot of the same individual animations at the same time?
