Just a note beforehand, I'm no PLC engineer. I'm an electrician/panel builder that can do some basic programming but thats about it

Got a project coming up that's a repeat of another project. Thankfully no PLC changes required but I've noticed something that seems odd - there are 2 outputs that show as used but if I use the find function they can't be found in the code. Any ideas of why this is?

Why is it that guidance note 3 seem more recommended/mentioned than the other 7 guidance notes?

Thinking back to my apprenticeship, I remember hearing plenty about guidance note 3 but hardly anything of the others, if they got a mention at all.
