带有phpexcel的arrayChunk输出一些数值

I have this code in PHPExcel that let me input values from cells starting from the E row. The looping of values from for each works. But I am having a hardtime removing the extra numeric values.

 $row_count2 = 1;
 $boldArray = array_chunk($bold, 3);
 $sheet->fromArray($boldArray,NULL,'E'.$row_count2++);

As you can see

There is another value on top of the values which I don't know how

Here is Another example of the values being shown.

I Hope someone could help me figure out the problem.
