Goodmorning everyone.
I am studying the excellent ABM for dummies tutorial, I cannot understand where the label [ABMaterial] is declared in the upper left corner as shown in the attached figure.

From the code it should correspond to the image logo.png present in the template subfolder \ Objects \ www \ template \ images but even if you delete it, the label remains.
I ask for help to understand the origin of this text label.

A thank you to everyone
