Not able to select the peg in the camera view?

If I select the element in the drawing view using point and click, only the drawing is being selected and not the peg

I have to select the peg layer from the network each time.

I used the method outlined here this is much simpler than the one given in the tutorials.

Why am I facing this and how can I fix it?
By fixing it, I mean, I want to be able to select the peg by selecting the part on the camera view.
