A double conversion is taking place.

This happens with one of the payment methods and your app. And there was a time when everything seemed to work fine for a couple of days. But mostly there is a double conversion.
I’ve attached a link to the video below to make it clearer.
The point is this: In WordPress the default currency is dollars. But there is also a plugin multicurrency (CURCY). With other payment methods all goes fine, regardless of what currency to transfer. But through one payment method that on the video I make a deposit. Everything goes fine. Even on the last page you can see that came 5 rubles. But in the profile wallet itself it counted 0.06 rubles! Do you understand? It counted it as dollars, but in the ruble currency.
