Cannot Click on properties of Default Node in the Editor

[Aqua]

Hi, I’m following through " Unity RPG Dialogue & Quests: Intermediate C# Game Coding" and I encounter this weird thing when I expand the default node added via script. I cannot click or change anything except first two text fields (ID and text) [Refer first photo].

When I try to click on it, the editor treat them as if they are not there, nothing happens, except I can hover on them and it would highlight them. I tried adding new nodes. The new one works perfectly fine. Just the default one. I have also tried to edit the default node after the new nodes added, still the same. So, I tried to expand both nodes at the same time and things get even weirder. The default node would be overlapped by new node [Refer 2nd Photo].

I also noticed that I cannot click on the “+” sign to add a new node while the default node is expanded.

I believe it is caused by the UI changes by Unity Editor overtime. But I have no idea how to fix. Please help. I’m using Unity 2021.3.3f1 version.

This is a bug in Unity for handling lists in the inspector which has reared it’s ugly head from time to time in versions of 2020 and 2021. You can remedy this by adding the tag [NonReorderable] to the List, which prevents the inspector from using the updated reorderable list (which is the cause of the bug).
