FX Translation IBKR

Hello y’all, I clicked through the various account statements today. And I noticed one point that I don’t understand. In the MTM statement I have a negative position for FX translations, which is then deducted from my total MTM profit, see picture below.

Now my question. What is this FX translation?

FX means foreign exchange. You have ‘lost’ money due to adverse FX movements. e.g. if you have USD assets and USD has weakened vs CHF.
