Missing Signals

I've checked both the old era and the modern era that I have installed both are fully up to date and also the PDFs which have the signal plans which look to confirm that certain signals are missing.

Welwyn Garden City K178 K177 K170 K173 K167 K168 K169

Hertford North K209 Limit of Shunt

Gordon Hill Limit of Shunt from Platform 2

Potters Bar K141/K142/K144 Shunt Signals

Alexandra Palace K117 Shunt Signal

Hornsey K97 Shunt Signal

Finsbury Park Shows Limit of Shunt but no actual signal
Finsbury Park K60/K66 Shunt Signals
Finsbury Park K51/K57 Shunt Signals

I make it least 23 signals that are missing from both eras of Kings Cross yet appear in both signalling PDF plans, what I want to know is 1. Is it just my setup that somehow is corrupted or does anyone else have the same issues?

If it's the latter then hopefully it be raised as a issue on Mantis.
