Mxc exchange doesn't provide fee information

Hello,
I received an excel file from mxc exchange with all my trades.
I have all the necessary information like received quantity etc except for Fee Amount and Fee currency.
Can I Leave the Fee amount and Fee currency colom open?
If I were to calculate the fee amount (mxc charges a fixed 0.2% per transaction) how do I know for certain in which currency the fee was paid?

Thanks
