Accounts Reconcile Function accounts corrupted

[Glenn2]

Each month I do a manual reconciliation on my accounts using the Edit>Reconcile Function.
This month only some of my accounts are showing and some of these have balances which are equal to the sum of several other accounts. If I look at the Portfolio Editor all of my accounts are showing and have the correct balance but the Reconcile View has them all messed up. I have shown a subset of the problem in the attachment.
One thing I did do in the prior month was a major tidy up /renaming of the Account Symbols I use for my Bank Accounts. If this caused the problem then it does not explainn why some renamed accounts are okay.

Hi Glenn2,

The problem is that you have those 3 investments with the same symbol. There is no such thing as an "Account Symbol", symbols are a property of the investment. When you reconcile, all the shares for a given symbol are summed up, and reconciled. Typically you would not have the same symbol for different named investments like you do there.

and fixed almost as quickly.
Many many many thanks
