Something with configuration (no buttons vertices, edges, faces on a bar)

Dear Experts,

Suddenly I found out that there are no buttons for vertices, edges, faces on a bar.
The 2nd question how to change a thickness of Z measurements of an appended object?
toolbox.blend (1.1 MB)

Thank you

I don’t know which one is the problem. :sweat_smile:
The Z-axis thickness change can be done by adjusting the scale to the Z-axis.

I meant there are no buttons to switch from vertices, edges, faces.
