Default value lost when placing a struct within a user defined struct

The default value of a child struct that is added to anther struct is not retained in the parent. An example would be if the child struct contains an integer, the default value when added to another struct will always be 0 regardless of the settings within the child struct.

1. Open the editor
2. Create a new structure
3. Name the struct Parent
4. Create a new structure
5. Name the struct Child
6. Open "Child" set the 1st and only member to an integer
7. Set the integer in Child to -1
8. Save
9. Open parent
10. Add two members
11. Set the first member to an integer and make it -1
12. Set the second member to the struct named "Child"

Result: The default value for the Child struct will be 0 instead of -1
Expected: The default value for the struct named child would be -1 when adding it as a member to the struct named "Parent"
