Balance doesn’t add up

Hello all,
Just signed up on Cointracker. Uploaded two csv files (one from Crypto dot com app wallet and another from Celsius).
After I tried to link both of them to Cointracker via the APIs but I was only able to link Celsius. Does anyone know if Crypto dot com generates an API or is this only possible in the Exchange? If only possible in the exchange, I wonder, will that capture the my transactions in the app?
Finally, for some reason the balance on Cointracker is not adding up when compared to the two balances taken together from Celsius and Crypto dot com. Any thoughts on what could be wrong?
