ADA Daedalus wallet showing transaction that did not happen

My ADA coin Daedalus wallet balance was fine till yesterday. Today its showing a big transaction dated 05-31-2020, while the actual wallet has the crypto. I just did my taxes for 2019 yesterday, could that have caused the change I see on cointracker. What changed?

Hi @aswathr18,

Could you please send us the ADA address in question to feedback [at] cointracker.io?
