You are misunderstanding what the program does. The appearance of the totals has nothing to do with whether there is a description. It is controlled by the number of line items of each type. If you have one debit and one credit, no totals appear, because you don’t need them. The debit and credit are the totals.
If you have a journal entry with more than one debit or credit, then the totals appear. You might, for example record distribution of profit to 10 partners, with a single debit to Retained earnings, but 10 credits to various partners’ capital accounts. The program will give you totals.
