The coin I bought was an error, but it disappeared

I paid 300,000 won for the deposit, 100,000 won for the sand, and 100,000 won for Omigo Saomg, but I saw it well for about two days, but suddenly the Omigo tax disappeared from the list of possession As you can see in the first picture, there’s no history of Omigo selling and no cash withdrawals The sale of 5,000 won sand on the top was sold without knowing it

I took it out because I thought you couldn’t see it because of the lag, but it came out well in the history The second picture is the current amount of coins
