Hello,
The dropdown you see next to the product is not there for you to select a currency but simply to display the cost against different currencies. The same information can be presented as a list if you prefer. The actual selection for the payment currency occurs on the checkout page, after the user selects “Bitcoin and Altcoin Wallets”.
Which currency did you choose on checkout?
The data you pasted seems to indicate that you have all the necessary data for the plugin to calculate exchange rates.
I am curious, if you meant that you installed version 1.1.14, or 1.1.4 of the gateway?
If you wish you can email me login details and I can have a quick look.
with regards
