Pregenerated report which pulls up records multiple times

Hello,

We have one report and which is send us by email every day by SQL jobs.

I just see drop date for one student multiple times.

I donot want Remilard-Kunz Virginia three times same value in drop date column.

How could I get rid of this column.?

I am also attaching code here to get clear idea.

Do you ever get this kind of situation before?

Any help would be appreciated.

Thanks
