Validating file corrupts transfer transactions which are correct before validation runs

Question

Error reported:

"The following transaction(s) involving transfers appear to be damaged.
 You should delete them and recreate as appropriate."

"Validate File" - damages some old transfer transactions which are perfectly valid before I run the validation. It removes 'transfer account' from one account but keeps it on the other.

Example:
    Transfer between account-1 and account-2, 
    Everything is okay with this transfer, 'go to matching transfer' works just fine from either account
    Run 'Validate File'
    Error reported and account-1 still has the transaction in the register but no account-2 is populated, while account -2 register shows transfer transaction with account-1 populated but 'go to matching transfer' results in an error telling to matching transaction exist.

The implication is the Quicken detected a transaction erroneously referencing the transfer and the attempt to repair the issue caused the subsequent damage.  I suggest you follow the guidance and delete and recreate the transactions.

Note:  Validate and Repair does not detect and correct all possible Quicken file corruptions.  I suggest only using Validate and Repair if necessary.
