Xero help needed getting rid of foreign currency losses / tidying up data

Accounting software: Xero Description of support work: I have just imported data for 2015 and 2016 and I need to have it checked, especially transactions and foreign currency losses. I would like to get rid of all the foreign currency losses from last year and I need someone to just go right ahead and do that for me, and then explain how I can do that going forward. I'd prefer someone in the UK and someone who can go through this with me over the phone please. Thanks Extra notes:
