Grid with Item does not work in four special cases.

Hello,

I use the Grid function to display a solution of Sudoku solver.

The following usage of Grid works successfully in many cases, 99%.
However, I found four special cases in which it do not work.
Would you give me a suggestion how to solve this problem ?

My Mathematica version is 10.0.2.0.
