Ash, if there's a conflict, there's the Bug!
More than a bug, this is also poor design.
This is the bug:
An object anchored to the left can scale to the right without problems, an object anchored to the right can NOT scale to the left.
The poor design is:
The way the anchor has too many options, and they conflict with one another.
That's why I'm suggesting these options as a clearer, un-conflicting way to position objects using the Anchor behavior.

Honestly man, I never thought it'd be so hard to make you understand these bugs, am I not explaining myself clearly?
I'll later post Anchor (V) with a capx, and a vid too??
