Paychecks Posted from the Wrong Account

I have found, scattered through the last couple of years pay checks posted to a savings account although the paychecks were written from a checking account. I tried the following:

1. On the left panel, click Transactions and select Chart of Accounts.
2. Choose the wrong account, and click View register.
3. Select the payment in question, and click Edit.
4. I found the check which was entirely gray, then clicked "edit", a page opens up that says "select the check you would would like to . . . " but before anything can be done/almost immediately up comes the check, and it says "paid from savings" with NO editable fields.
   
5. Change the posting account, and click Save and close. (This is not a possibility.)
6. Click Yes.

Can this be corrected?

1. I have never paid  anything out of savings. Other than interest income the only other entries are these random paychecks, both written & direct deposited and a couple of tax payments.
