Binance transactions messed up after several years of use

Describe the problem:
I have been using Koinly for years now to do my taxes. In an effort to solve a couple of missing cost issue on a binance transaction i tried to export transaction history from Binance and import to koinly anew plus reuploading CSV exports from earlier years, as i figured it might have its roots in an older transaction.

Instead of solving the couple of missing cost issues, i now have 73 (8 pages) of missing costs issues and no idea how to solve it.
Can i roll back somehow?

If you have any questions or ideas, please shoot! Thanks in advance =)

Which exchange/wallet is this regarding?
Binance.com

How did you import data into this wallet?
Binance “Generate all statements” + reimporting older .csv files i have downloaded January 2021.

What have you tried to fix this so far?
Tried “resync from beginning” on my binance wallet/API + reimporting ALL my .CSV files from the previous years.

Hi Frederik, Did you manage to fix the issue with missing Binance transactions? I’m having the exact same problem. Do you have any advice?

The most likely reason for the tx errors is that the reporting format changed and you now either have duplicates or have overwritten old transactions.

I also have this exact issue.
