Let me rephrase - I've done that in every implementation I've done for the last 2 years. Never had a problem with marking them reconciled in standard bank rec and then having them visible again in the account rec page unless someone edited them after I marked them reconciled. In which case editing the first reconciliation, and then unchecking it. Then saving, then editing it and checking it should resolve.

Hey! I did a bit more testing and I think you're right thanks as ever. When you change banks sometimes the transactions appear, sometimes they don't etc. Eventually they do disappear. The confirm matches page is buggy AF it seems. 🪲
