Chase updating wrong account in Quicken

ConnieMS

I have two accounts that have the same last 4 numbers. The name is right when they are linked but the transactions download to the wrong account. I have to delete the wrongly downloaded transactions and mark the right ones cleared manually. Please figure out how to fix this.

I would deactivate both accounts, restart Quicken, then activate only ONE of the accounts.  Do a download and make sure they went to the correct account.  If correct, then repeat for second account.

If you do both at the same time, maybe, either you are Quicken is messing up (I'm not pointing my finger at either side), but by doing them in stages, you can ensure that they are hooked up correctly.
