Hi Matthew.
Making the change does not change previously posted transactions, since that causes a change in the transaction itself. You will have to edit all of these transactions, or reverse them and re-enter them, for these changes to take effect.
The easiest method is often to Full Edit, make a small change somewhere (like a space at the end of the description), and then re-record. Review the transaction first to make sure it is changing the actual transaction, and not separating out the PST.
Thanks!
