BP Soft Reference issue

Hello, i’ve a problem with unreal’s soft references system. I’ve A_BP that has a soft reference to B_BP. If I launch the reference viewer to A_BP, i see that this refereces is a HARD reference. Why?

It’s a “hard reference” because the target object is currently “valid” and “alive”.
They are a “soft reference” when the object is “valid”, but is currently unloaded (which can later be synchronous loaded).

How to unload this object? They are only in the content, not in the map

Were you able to craft a way around this?
