After our equity plan amendment, Carta's FMV seems to be pulling from the wrong date

We amended our equity plan in March 2026 to point to a new share class: Class A Common. Now when I look at our 409A valuation from November 2025, it's showing the FMV tied to Class A Common instead of Common. Class A Common didn't exist until March. Has anyone run into this? Is this something I misconfigured on the amendment, or is Carta pulling the wrong share class for historical dates?
