It’s asset I bought from asset store, a FBX that stacked several models:
After I import it into UE4, it’s all models combined together. The problem is that I don’t find a way to separate them again:

As reference, when I import it into Unity, I get this:
Note there are several separate ones like “hunter_red” or “Knight_RED”
When I try to add it to the scene, at first it was combined together, but I can reserve just one of them by deleting all other ones:


How can I get the effective result like in Unity? Please see the FBX in google drive if necessary:
