Sorting Rows Ascending Numerically


I right click on the column and select "Sort Rows" and select "Sort Items By" the name of the column. They arrange numerically but it's broken up into numbers 007-099 showing up below 103-180. I want the 007-099 numbers to show up above 103-180 (as it should).

My thought is that the numbers are "text"? But I can't find where to assign the type of content in the cell.

Any help would be appreciated!
