EQS Generators are becoming blank after deleting and undoing the node and restarting the editor. Any tests placed on the generator are still visible, but the information on the generator node is blank.

2. Create a new Environment Query (ensure to enable the Environment Querying System in Editor Preferences->Experimental
3. Open the EQ and add a Points:Grid test
4. Right click the Points:Grid node and add a Distance and a Dot test
5. Save & Close the EQ
6. Open the EQ
7. Delete the Points:Grid node
8. Undo the deletion (CTRL+Z)
9. Save & Close the EQ
10. Restart the editor
11. Open the EQ

Result: Notice that the Points:Grid information panel is now blank on the node.

Expected: The test information would still be visible on the node.
