Datagridviewautofilter.dll problem

Hi All,

I'm trying to use Datagridviewautofilter.dll on a datagridview that is bound to a data table that is pulling information from SQL Server.

It's working fine except for the fact that on the first column you can't see the first value in the drop down list. It's fine on all other columns, I've tried on multiple different tables and get the same problem, always on the fist column. 

Any ideas?
