[AccessD] Union Query WHERE Bug?

Can anyone explain why this query returns one record, as it should...
 
SELECT quniCEIncompleteCredits.*
FROM quniCEIncompleteCredits
WHERE (((quniCEIncompleteCredits.RepNum) Like "8222")); 
 
And this query returns no records?. 
 
SELECT quniCEIncompleteCredits.*
FROM quniCEIncompleteCredits
WHERE (((quniCEIncompleteCredits.RepNum)="8222")); 
 
 
Using Access 2000. 'quniCEIncompleteCredits' is a union query.
 
TIA,
 
Myke
