Erroneous Cost Basis off by 100X

A few of my Tether transactions are being reported with massively incorrect cost basis figures. One example is 5,017USDT reflecting a cost basis of -$9,097,519.02.

Of my 91 USDT transactions, 18 are way off like this. Some are manual uploads and some are API from Binance, so there’s no pattern.

Is this a known error and how do I fix it?
