It's because you categorized it as *smbase-printing not 
*smbase-override.  Because it wasn't marked as an override, MC sees you 
as having "stolen" that method (ie, maybe you control both packages and 
were moving it from one to the other).  So when it then disappears from 
SMBase, it gets removed from the image.  If it were marked as an 
override and then disappeared, it would get reverted back to the 
VersionNumber version.

What you should do is change it to *smbase-override now, and then 
you'll be relatively safe to remove it in the next version.

Make sense?
