How to stop Treenode text from being overwitten?

Question

I am having problems where the text displayed for my treenodes is being replaced by a reference to the class I am storing in the tag property.

I have a simple form I have built using the form designer in Visual Studio 2019 that has a treeview control that I populate using with treeNodes. I have a custom class called LineItem that stores all the information associated with each node that I store in the tag. I then set the text property of the node using the ToString function I set up in the class. The result however has been that every node ends up displaying the text PlankForm.LineItem, PlankForm being the project name. Below is the code I am currently using to add the node.

//Create new node in level match group with appropriate LineItem
TreeNode treeNode = new TreeNode();
treeNode.Tag = lineItem;
int index = lineItemTree.Nodes[lineItem.levelMatch].Nodes.Add(treeNode);
lineItemTree.Nodes[lineItem.levelMatch].Nodes[index].Text = lineItem.ToString();

I have tried setting the nodes text property both before and after adding it to the tree but both seems to have the same result.

The problem is in the ToString function. It was written in the code as a property named ToString instead of an override of the ToString function.
