OK, first things first.
I only mentioned the csv export because I thought you wanted to migrate an existing transaction from one machine to another. If you have not performed any successful transaction yet, just ignore the export/import thing.
Also, if your IPN history is empty, that means that the CoinPayments platform never attempted to notify the plugin of any deposits. Could it be that you have not setup IPN correctly? Please confirm that you have followed the installation instructions on https://www.dashed-slug.net/bitcoin-altcoin-wallets-wordpress-plugin/coinpayments-adapter-extension/ and in particular the part where you create an IPN secret and set in the coin adapter settings.
