Check Integrity Dialog is Blank

When editing a horizontal or vertical alignment, it is often a necessity to utilize the Check Integrity command for the alignment you are working with.  But what do you do if you have a valid alignment with numerous elements, but the Check Integrity window is COMPLETELY BLANK?  

What has likely happened is the columns have been minimized   Hover over the far left side of the 'Header' row.  When you see the double arrow (left-right arrow), click and drag the column over to the right.  Repeat this process until you get all the columns widened for viewing.
