Why is the closing price and current price of overseas stocks displayed differently in Heromun HTS?

I checked my balance in the early morning and felt good, but when I looked again, I saw that my balance had decreased significantly.

I did something and looked again, and there were cases like the ones above.

As you can see, the final transaction price is $63.38 and the bid price is also stacked at $64.

Strangely, the current price is displayed as 55.46 and the balance is also calculated based on 55.46.

This has happened not once or twice, but often, and I would like to know why this is the case.
