Notes
​
Omitted transactions
All transactions starting with underscore are omitted from the Koinly CSV (i.e. _LP_WITHDRAW).  This means these transactions must be imported into Koinly manually (or ignored where appropriate).
​
Can I import CSV multiple times?
Yes, for Koinly.   You may import the full CSV multiple times and Koinly will detect duplicates and omit them.
​
Tips
You may want to import partial CSV first as a test.  It's cumbersome to undo a large amount of transactions.
Quick delete: there's no bulk delete function.  However, the quickest way to delete transactions appears to be deleting transactions page by page via the following: select one transaction -> go to bottom of page -> select icon to select all on page -> delete
