@Deadwood Al  Not seeing it on my end; could be a custom column someone added to your books.

Either way, you can remove columns from reports without knowing what it is tied to in the Columns listing.

You may notice a series of three vertical dots to the left and right of each column name.

Hover your mouse cursor over those three dots, then click and hold the left mouse button as if you were going to resize the column. Then, drag the cursor to the left until you have passed the next set of three vertical dots.

Release the left mouse button and the column will be removed from the report.

Reports only require that you have one column active, so you can remove basically as many columns as you need to in this way. Could even memorize the report if you don't want to have to do this every time.
