NullReferenceException: SerializedObject errors after altering SO

How to reproduce:

1. Download and open [Internal link]
2. Open Level1 scene
3. In Project view find and open "NPCChatData.asset" in Inpector
4. Expand Element 0 > Chat Items
5. Enter Play Mode
6. Notice the Chat Items list ends up with just 1 item
7. Click + sign to add new item
8. Exit Play Mode
9. Observe Console

Expected result: SO returning to the previous state(Chat Items to full list - restarting the editor it does) and no errors

Actual result: SO stays altered in Inspector after leaving Play Mode and errors start spamming in Console while the SO is selected

Errors:
