### Summary

When copying a value from an array to another one, the values get linked, making this not usable because it creates a behavior where you could delete data from the other one without knowing.

### Please select what you are reporting on:

Unreal Editor for Fortnite

### What Type of Bug are you experiencing?

UI/Tools

### Steps to Reproduce

Have two device with and array of same custom data for example a concrete class.  
Copy and paste the values from one to another.  
Values get linked, to check this, modify 1 of the arrays, check the other one and you would be able to see them changed.

### Expected Result

Values should be copied from one to another, but not be linked. So changes in one should not change the other one.

### Observed Result

Arrays get linked, changing one, affects the other one.

### Platform(s)

UEFN, PC
