I am working with parts downloaded from McMaster. This is a simple weld cap. I noticed that the Front, Top, and Right views are inconsistent between the feature manager, orientation window, and in the drawing views palette. I noticed in the views pallet some views have a (A) in front of the label. I don't know what this is and any help on this issue would be great! 

Here is a flash video of my issue:
