USD Coin (USDC) Inaccurately Showing Large Loss Amount

USDC is showing up as a massive loss amount in my account (approximately -$180k), when it should be either an insignificant gain or loss, given the fact that it is a stable coin. I have tried to figure out why this is the case, but can’t find any reason why (all of my USDC transactions appear to be accurately classified). All other stable coins in my account correctly reflect either an insignificant gain or loss. Any ideas on why this is the case?

Please check this post and let me know if that is not the issue:
