Employee lied about education [N/A]

Before I was with the company and employee was hire and on their resume they stated they had their degree in economics. Their role is in accounting, but more of a clerk role, so they don't need a degree.
It has come to light that this person does not have their degree and has never attended university. Which, for this role, is totally fine. However, the dishonesty has left a bad taste. The human side of me wants to address it because I HATE when people are deceitful, but the professional side of me says let it be and not stir the pot.
WWYD? Address it or let it be?
