Posting Date vs Transaction Date

Until the latest update, I was able to post transactions as they happen and, when I downloaded my bank info, they would take on the transaction date as entered OR download as a duplicate transaction. Now, all transaction dates are changing to the posted date and this is starting to take me a lot of time to correct. I need to know when purchases, etc, were made and NOT when they cleared the bank. I see this issue has been dealt with before but all threads have been closed so I had to start another one. The option of defaulting to the transaction date isn't in the preferences like was shown in some people's examples. So, how do I change it back to the transaction date without editing each transaction. It's taking more time than I care to take.
