I have a Vanguard Roth IRA account and a Vanguard brokerage account. Below is a snapshot of my Roth portfolio tab. For March 1, Quicken recorded the market value at 80% lower than the correct amount. For March 9, it recorded it at 290% higher than the correct amount. On those dates (during and after trading hours), I logged into my Vanguard accounts and checked the market values and they were correct on the website (they didn't match Quicken). This means that the problem is with Quicken, which recorded the wrong amounts on March 1 and March 9. Is there a way to fix this? Thank you in advance.
