Try to set layout's matchMinorSize="true" and specify preferred size for 
Rule[Entities|Actions]CompartmentFigure.

Generally, working with layouts (not necessarily with GMF's) one should 
doublecheck his expectations :) Even without the changes the diagram looked 
to me like using FlowLayout - Rule's label and both compartment were 
layouted in a single row (though size of the compartments was small, it's 
obvious why - no size preferences (minimum/preferred) were specified in the 
model).

That's known issue, https://bugs.eclipse.org/bugs/show_bug.cgi?id=149516

2. Already covered with adjacent posts.

3. That's a bug (https://bugs.eclipse.org/bugs/show_bug.cgi?id=150816), 
although I believe it won't  hurt your case - one you map RuleEntry's label 
to domain attribute (e.g. RuleEntry.name), the problem will disappear. If 
you really need label not backed up by domain feature, let me know and I'll 
describe the workaround.
