Instanced Widget Property is not saved after compile if marked as EditInlineNew

When an EditInlineNew Instanced property exists within a nested user widget, changes to the property are not saved after compiling the widget blueprint in the editor.

1. Download attached project
2. Generate project files and open the project
3. Open MenuTest widget blueprint
4. Select Menu Wiget rom Hierarchy tab
5. In Details tab, add element to Button Infos array and set to TGUIButton Info
6. Compile
7. Expand '0 -> ButtonInfo' and enter a value for Display Text
8. Compile

Result:
The TGUIButton Info set in step 4 is lost upon the second compile. This also occurs if another element is added to the array at step 7 and then the blueprint is compiled

Expected:
Element reference is saved when the blueprint is compiled.
