Those two tables contradict each other. The first says runny nose is not a symptom of COVID-19, the other says "sometimes".

This just shows how little we know (and/or how much misinformation there is about it), and that a differential diagnosis based on symptoms is basically impossible (at least for a non-expert).

it's also quite possible that some people suffer both from covid-19 and the flu or a cold at the same time and the symptoms are being mixed up.

Then maybe this [1] clears things out. Probably differences in understanding what "sometimes" means. This shows specific frequency/percentages.
