PWA does not recognize the word 'canon'

Michael Loucks

PWA insists that the following passage ha a 'confused' word when 'canon' is a correct word.
"It's tricky, because of the canons. He's still titular bishop, but Bishop PAUL has been appointed _locum tenens_. That means he's responsible for administering the diocese until such time as Bishop ARKADY is able to resume his duties or a new bishop is enthroned."
'Ignore' is not preserved across grammar checks and there is no option to add 'canon' to the dictionary (as it is a legitimate word).

As an aside, I've found numerous instances where PWA makes a complete hash of theological and religious terms., which is especially true when quoting scriptures (Christian, Buddhist, or Muslim).
