Unable to initialize a structure in the blueprint!

Hey. I have a problem. I am creating a structure in C ++, exponent create an instance of an array structure in my class to initialize it to the blueprint, but when I try to add any actor in my structure - it is not added. “None” is always displayed. Please tell me what I’m doing wrong? In the last version 4.13 it was fine. This is a mistake of the new version?
