Hello, I added a new bank account to my account and now all of my January 2020 etsy transactions are showing doubled. Why did this happen and how can I fix it?

This issue is already reported to our engineers, Hello79.

While we're waiting for a fix, you'll have to delete the duplicate transactions manually as a workaround. Here's how:

1. Go to the Transaction page.
2. Select the transaction.
3. Click Delete.
4. Select Yes to confirm. 

I'll add the reference on how to exclude or delete transactions. 

I also suggest reaching out to our customer care support. We're taking notes of the users who are affected by the issue. Here's how:

1. Click Assistant.
2. Enter "Talk to a human" in the description field.
3. Click Talk to a human.
4. Select either Message an agent or Get a callback. 

You can post anytime in the Community if you have other concerns. We're here to help you. 

The issue is that it's an entire months worth of transactions so it's not feasible to sit and mark each one as duplicate. 

This issue with that is that it is a months worth of transactions so it's not feasible to mark each transaction as duplicate.

I appreciate you getting back to us, @hello79.

While our engineers are working for a fix, you can consider deleting all duplicate transactions instead of marking them as duplicate. Rest assured that they're diligently working on this issue.

To ensure you'll get an update about the resolution status, I recommend contacting our Customer Support Team. They have to collect personal data to add your company to the list of affected users and provide this investigation number for easy tracking: INV-41299.

Thank you for your patience while we're working on this. Please know that you can always get back to this post if you have any other questions.

Hopefully the fix is quick, there are approximately 400 duplicate transactions so I don't have the time (nor do I want to) sit and delete or mark as duplicate. Each duplicate transaction is the exact same as the other so there is no way to filter them out.
