Unable to reconcile Credit card since starting a NEW MYOB

We previously had MYOB and we decided to transition to a new MYOB account to keep this one decluttered. But since moving to this one in July i have been unable to reconcile the bank card.

I have checked our Balance Sheet Balances and adjusted them in the opneing balances, I have spoken on the phone and on chat to MYOB and noone has been able to help me.

I saw this answer on a previous post which I have posted below and I have done these steps and our calculated balance does not match our ending balance. There is around a $3k difference. 

I am hoping someone can help so that I can reconcile this account our bank account reconciles just not the credit card.

The first thing to check in this situation will be if the bankfeeds have that data on our end, therefore, can you please send me the following information by a Private Message:

• Serial number
• Last 4 digits of the credit card
• Date and amount of these 3 transactions

Also, since you have mentioned that the balance has changed automatically after deleting and re-entering the transactions, can you please perform the following test and confirm if the figures match or not:

1. On the Reconcile Accounts window:
1. Enter the closing date of your latest bank statement in the Bank Statement Date field.
2. Enter $0.00 in the Closing Statement Balance field.
3. Select all transactions as cleared and take note of the Calculated Statement Balance .
2. Go to Find Transactions > Accounts tab.
3. Select the bank account you're trying to reconcile.
4. Enter the closing date of your latest bank statement in both the Dated From and To fields.
5. Press the TAB key on your keyboard and take note of the Ending Balance in the bottom-right of the screen.

If the Ending Balance is not same as the Calculated Statement Balance, please let us know.
