Excel Filter Problem

[purceld2]

I have a filter that I use where I enter the value "BK146" but the filter brings back the following

BK146
BK1465
BK1466
BK1460

How can I stop the filter bring back anything other than "BK146"

Thanks for your help in advance.

Which version of Excel are you using and how are you setting up the Filter?

I am using Excel 2007, and if I set up a Filter and select the "BK146" option, that is all that it returns for me.
