Label not adding in physics editor for phaser 3 with matter js

Phaser 3
1

I was using phaser 3 with matter js and physics editor to make a body for my tree. I gave the label in the textbox as tree, and the json confirms it. But using the collisionactive event in matter, the tree has a label of ‘’ , empty. Why so? At the moment I just used the label as empty to check it, but I would like to give it a proper label. Adding tree.body.label ='tree' yields the same result. Any help is greatly appreciated. Thanks.

Just inspected the json and found that there are 2 label properties:

{

				]
			}
		]
	}
}

After making the second label(the one in the fixtures array) to tree, it worked!
