I'm using HM3 and i play on Microgaming, some MTT's get the prizes registered in USD currency but were actually paid in EUR.
I have EUR as my default currency in HM3 and since i noticed this, I edited the currency exchange rate to 1 so at least my net winnings are correct.
But I can't edit or change the Currency in the MTT manually so this doesn't happen.
I have no tournaments were the buy-in or the prizes are in USD.
Also couldn't find any way to fix this in your software.
