Unwanted Drop Down Arrow Appearing on Chart

I had made an income/expense chart and wanted to copy it into a new tab so I could have a tab for each month but when I copied the original and pasted it into a new tab it made a drop-down arrow on each of my columns that I do not want there. How do I get rid of it?

What I mean by drop-down arrow is a white box with a black arrow pointing down and when I click on it it gives me Sort Options A to Z or Z to A. I have no need of this.

Thanks!
