Looks like real amount is 31.875 (4x31.875 = 127.50). Probably you set currency format to three decimal digits, add few transactions, then set it back to two decimal digits: [url=http://www.alzex.com/help/currency-edit.html]http://www.alzex.com/help/currency-edit.html[/url]
Open such transactions and enter amount again (simple double click on it then click OK to rewrite data).
