Can't Delete a 1099-B Entry

I made a couple of manual entries from a 1099-B.  It turns out I will be better off importing the form this year.  But I am unable to delete the sales I have entered.  It appears to be a display problem.  On the summary screen the display is truncated so there is no trash can icon.  I tried closing the file and reopening it - no joy.

Using desktop version in MacIntosh.

 

Any suggestions?
