In general you should enter ALL your wallets and ALL your transactions. The more accurate is the result in your account. And of course the Kraken transactions would gave your portfolio a more complete picture.
KuCoin could be imported via API, Coinbase as well with no API limitations by the exchange.
TradeOgre we do support via CSV.

Those FAQ articles are helpful to mitigate negative coin balances - in most cases transactions - either trades, deposits or withdrawals are missing:

The reason for possible negative balances is that CoinTracking calculates the balances out of the transactions happened and of course imported.

If it does not help I suggest to check your account individually. Please send us a support ticket or an E-Mail to support@cointracking.com with your CoinTracking username (login).
