Error with Merrill Lynch downloads

gslaby

Quicken Classic - Version R65.29, Build 27.1.65.29. I have three Merrill Lynch accounts. The first time I used the EWC+ update all three accounts downloaded and reconciled great. The second time I updated the accounts one account (A) was perfect but the other two (B&C) had the transactions switched. The transactions for B were assigned to C and the transactions for C were assigned to B. I disabled automatic updates for all three accounts and used the statements to reconcile (frustrated).

I went into the account list and account B has the correct nickname but has account C's account number and C has the correct nickname but B's account number. I have no idea how this happened. Is the remedy as simple as switching the nicknames to match the account numbers?
