I can't reproduce this with a random ticker. Why don't you tell us the real ticker instead of a fake one?
I had already tried a random stock. I tried DVN and still can't reproduce your error. Which Portfolio View are you looking at? Maybe time for a Validate & Repair?
PS: sorry it dropped like a stone since you bought it. 😓
I have never had DVN in my portfolio until I tested it for you. Price history looks fine. I think you may have data corruption.
