Crazy inaccurate transactions on 8949

I have meticulously integrated all of my transactions (over 6k of them) into Koinly and everything on my dashboard is accurate. Then I print out my 8949 and there are crazy transactions on there that never occurred:
6.34 ETH bought and sold on February 9th.
14.96 BNB bought and sold on March 13th.
some mystery coin bought on March 13th for 3k and sold on march 28th for 9k.
6.8 ETH again shows up on February 9th bought and sold
49 BNB again shows up on March 13th bought and sold
13k USDC bought and sold on April 5th
14500 Matic bought and sold on April 10th
6.6 Quick bought and sold on May 7th
867 Fish bought and sold on May 19th
DFYN LP worth 4800 bought and sold on June 5th
These show up as wash trades so they don’t really affect my capital gains…but they make my total transactions look gigantic and way inaccurate…showing that my cost basis of $226k with proceeds of $227k. This is grossly inaccurate and i don’t want to submit this for my taxes.

Why is this happening?

I have the same exact issue. Really strange. I have sent an email to support but I have no idea why this has occurred. I similarly see massive bitcoin transaction (3.5 btc) and the same for ethereum, both of which never occurred and are not present in my actual transaction history on Koinly. Really hope this is fixed in the next month…

Koinly is aggregating your transactions because there are so many. The dates lists are the first date you purchased a particular token, and the first date you disposed of any.
