What you have probably done is create Lookup fields on the table level. This is NOT recommended see Evils of Lookup fields.
So what is actually being stored is the ID, not the description. This is correct design, but there are different ways to display the name. The standard way is to do your lookups ONLY on the form level using list controls. The combobox wizard will set up a combobox that hides the ID column and displays the description column.
For reports, your report should be based on a query that includes the main data table and any tables used for lookups so you can bring in the description column.
