Language Cloud termbases -- what's with the check box in front of termbase names?

In the Help text for Editing termbases, this is step 6: "Select the check box corresponding to the termbase whose details you want to edit, and then select Edit."

No. If I select that check box, the only thing I can do is delete or refresh the termbas. To edit (and in fact to select any of the other buttons above the list of termbases), I must NOT select the check box but select (click in) the row of the termbase name.

If I select the check box, the only actions available are Refresh and Delete. But they are available as well when I have selected the row. So what's the point of the check boxes?
