Ssrs 2016 ID cards

In a new ssrs 2016 report, I need to generate student id (identification) cards. The requirement is to have 12 unique students print in each regular sheet of paper that is 8 1/2 by 11 inches. There will be 3 columns and 4 rows. On one sheet of paper, there should be 12 different student id cards. No student should get more than 1
student id card.
Right now I am able to unique students in column number 1. However in column #2 and column #3, the same student information is printing that is in column #1.

Thus can you tell me and/or show me how to get unique student information in all 3 columns of the ssrs 2016 report?

how about this

Thank you for your answer so far! I tried the example listed above where the vertical alignment is center and the number of columns=3. I ended up getting The same label printed on 3 labels on the same line. Do you have any other suggestions?
