Simple Query Doesn't Even with Data

I have a simple database with table, "map_table", and coulmn,
"company_letters".  The database is populated and the first row
contains a value of 'abcdefg' in the company_letters column.

If I do a select * without a where clause I get the expected results. 
However, when I execute the following select statement I was astonished
to see no results come back.  

Any idea what could possibly be wrong here?  

I've verified the data a 100 times and am totally perplexed.  Thanks.

SELECT *
FROM public.map_table
WHERE company_letters = 'abcdefg';
