duplicated transaction with cleared/reconciled status which is not, and impossible to delete

Hi, I have a few cases with the same problem: a duplicated transaction, not checked for neither cleared no reconciled status, impossible to deleted from the activity log! It is a transaction from October 2022, whereas everything has been reconciled until June 2023. And when I go to reconcile July 2023, I see those transaction in the feed. There is a dozen that I am not able to delete. I tried to delete them from the Activity tab, but whereas they do not have any check on the reconciled/ cleared status, I am getting a warning in red saying that it is not possible to delete the reconciled/ cleared transactions. Is it just a bug?Please help.
