Steps to reproduce:
1) Open attached project
2) Open the test scene and open the NoGizmos graph
3) Add new property that has an interactive gizmo (position in this case)
4) Select graph asset and in inspector enable Show Property Gizmos then click Edit Gizmos
5) Observe that gizmo is not visible. If it is visible try dragging it – it will disappear with no values updated.
Note: If you select the property directly from the blackboard you can interact with it. However notice that graph's inspector still doesn't sync actual values.
