Multiple Explanations with Numerical Constraints

[Gauntlet173]

In some situations with code that includes numerical constraints, in scenario editor, there seem to be duplicate answers generated that vary only in the names of the variables to which the constraints are applied, even if those constraints don't appear in the explanation displayed to the user. There are also duplicate explanations that differ only in whether the constrained variables exist.

I've attached a Blawx file that I think may be replicating this error. It's a basic numerical constraint, and when running the test scenario, 2 answers are generated. The 2nd answer includes 3 explanations, 2 of which are identical
