The description for some accounts is pulling the max number of characters and that is why it appears that the amounts are going onto the second line. In order to resolve this you will need to run the report again to note the accounts that are affected by this.
Once you have a list of accounts, select Accounts, Chart of Accounts, and click the edit button on the accounts that are pulling oddly on the report. Double-click on the description and note that the description field is pulling blank characters. Remove the blank characters for the necessary accounts and run the report again.
