Couple of things I will assume first:1. There was no change in number of shares/share swap/merger of funds as part of this action.2. This is a name change only.3. You have processed a Corporate Action/Name Change transaction.If all of those above hold, then I suggest going into the Security Details and Edit Security Details and Uncheck "Matched with online security". Click OK. Close Quicken. Reopen Quicken and complete a One Step Update. Then go to that account and it should ask you match the security to your holdings, and then should remember after that.As always, back up your file before trying any solutions you are recommended in the QC.
