Why are my stock warrants showing the wrong expiration date.

I’ve checked every financial document for this company 10qs, stock issuing docs, debt etc and they all show the correct date but vanguard and almost every other exchange shows a date of expiration two years earlier than it should be. I even reached out to vanguard and they confirmed it is wrong but I’m afraid my warrants will be lost at the early expiration date when it comes around. What can I do to protect myself aside from selling.
