File based import: match transaction that is already reconciled? - eviltoast

I only recently started using file based import (and it’s actually really nice), but I keep running into this issue where imported transactions aren’t matched to reconciled transactions and they end up being just duplicates. How do I get around this?

When I want to manually match it, only transactions that aren’t cleared are shown.

Do I just delete them every time? Should I remove the reconciled transaction so the imported transaction is memorized and doesn’t pop up the next time? Should I try to remember the exact import date and only use the transactions after that date?
