How do I remove the empty array

As you can see in the pictures i made below, The 5th row is empty with NULL in it.

I don't understand why its happaned.

Please help me

alex3160 I don't use arrays frequently but isn't there an action called "DELETE" to remove array element.

OHH

Just found the answer.

From the begining the array was with 1 width, So its not empty from the beginning.

Now i am remove the 1 and set it empty and its work.

THANK YOU FOR FAST ANSWER AND TRY.

An array of size 1, 1, 1 starts with 1 blank cell. if you push 4 things to it, it will then have a width of 5. Try starting with array size of 0,1,1.
