Can't Rearrange Sorting Layers

In the Tags and Layers menu I tried making a new Sorting Layer called background and moving it behind the Default Layer, but I can't rearrange the layers. I tried clicking and dragging the two bars on the left side and nothing happened. I also tried making another layer to move, restarting Unity, and restarting my computer. None of these did anything to allow me to arrange the layers. Am I doing something wrong or is this a bug?

 

You can only sort in the sorting layers column.
Just click and hold while moving the sorting layer to the required position.

 

Hi Microraptor,
I´m having exactly the same problem, did you figure out how to solve it?

 

Also having the issue where i cant seem to be able to move a sorting layer.

Tried locking and unlocking it and in neither mode it moved.

Not sure if it's relevant but i'm using the 2019.3.0a2 linux editor version (downloaded through hub)

Error that is reported in the console:

I have the same problem.

I had this same issue with NullReferenceException errors when trying to rearrange sorting layers. Uninstalling and updating to 2019.3.0a11 fixed it for me.
