Exchange imported from shows balances in EU + GBP that I do not have

I have an error in the CSV import of the exchange that results in a wrong balance.
It shows me amounts of of EU + GBP which I do not have, so the final balance doesn’t match my wallet. Anyway to fix it?

You can go to your full data set and manually make corrections or you can send us a copy of your CSV file and we can take a deeper look.
