Trial balance, detailed transaction listing and other reports are displaying an *overflow* message in the "Balance" column of the transaction listing and in the trial balance does not reflect the account at all.
I have followed some earlier advise which suggested that the transaction amount be re-entered; the transaction amount be reduced to half or less to reduce the number of characters and a full stop be entered into the memo field. None of these efforts had any effect. The amount entered is of similar length of earlier amount entered and the "balance" amount has not increase in character length from the last displayed amount which is in the same month.
I have only experience this issue after the upgrade from 2017 to 2018.
