Reconciliation problems I don't know how to fix!

So from the screen you posted, it looks like a reconciliation was done two times on 8/19/25. The discrepancy amounts offset each other. So the first reconciliation that day was wrong, and the second one apparently corrected it. If you click on the one with the 13 discrepancies, you can see which transactions were added, deleted or changed. There were two reconciliations done on 7/18, and the sum of their discrepancies plus the 6/18 reconciliation discrepancy total to zero. Thus your cumulative difference is not WAY OFF — it's zero, as the screen shows on the bottom left.

There are several things you could do. One is to simply ignore these couple months which were reconciled incorrectly and then corrected, since your balance and records are now correct and will remain that way going forward.

You could also try to re-reconcile the reconciliations which show a discrepancy, starting from the first one which is off, and then proceeding up through the others. (Please make a backup before you start this, in case things get worse instead of better! 🤣)

Or, if the individual monthly reconciliation history isn't important to you, you could do the nuclear option of clicking the Clear History button, which will erase the record of all the reconciliations. You could then do one all-encompassing reconciliation from the beginning of time up through 10/20 — e.g. enter the 10/20 balance, then click on "Mark All as": Cleared, de-select any recent transactions which were outstanding as of 10/20, and the balance should be zero; click Finish and everything will be reconciled in one 10/20 reconciliation.

The last option is to Clear History, and re-reconcile the 10 months from January through October. (Your screenshot makes it appear the history doesn't got back further; this obviously wouldn't be a viable option if you had 15 years of transactions but for 3/4 of one year, it probably wouldn't take you too long.)

I have advocated for a feature which would let you clear history only back in time to a specified reconciliation, so you could then re-reconcile the recent months which got messed up. Such an option would be helpful for someone in your position with a few messed up months and extraneous reconciliations. So far, the Ice hasn't received many votes, but I'd encourage you to add your vote in this thread, because such a feature would make it much easier to resolve your situation.
