UDN Link: https://udn.unrealengine.com/s/case/5004z00001ndG9mAAE/tarray-uproperty-element-do-not-get-the-correct-default-value

In C++:

1. Create a UStrcut(MyStruct) with an UProperty such as bool or int32
2. Set a default value to variable
3. In other UClass create a UProperty type TArra<MyStruct>
4. In the editor any time you “add” a new struct will show the right value but also it shows reset arrow
