default values on a Make Struct pin that has been removed are incorrect

If a user creates a struct, uses a Make Struct node, removes a member from the struct, and then adds the value back in the value will not always be correct.

1. Create a New Struct
2. Name it "Test"
3. Add two members to the struct
4. Make the two members integer values
5. Set the default values to -1
6. Open the level blueprint
7. Right click > Type Make Test
8. Notice the values are both negative 1
9. Open the struct
10. Remove the second member of the struct and then add it back exactly how it was
11. Open the level blueprint
12. Notice that the value for the second member of the struct is now 0 (attached image for reference)

Expected: The second member's value should reflect the correct default value
Result: The Default becomes 0

Make struct in Blueprint does not uses default values
