With unitless V all is OK
I don't think you're looking at a bug, but more likely the effect of your default TOL setting on how close 3 sq cm has to be each element of V (don't forget Mathcad internally converts sq cm to sq m).

As Stuart and Fred already have written, its not a bug, its a feature 
Hmm, but a very annoying one. Changing the value of TOL to a much lower value may have undesired side effects on other numeric calculations.
In Mathcad we also have "Match" (note the capital "M") with its modifiers , but unfortunately there is no modifier "equal" and equal means also here wrt the base unit and the value of TOL.
So the only way to avoid this "feature" (which I consider simply a very bad implementation) is to write your own match function:
This also copes with the often annoying error which is thrown by the built-in match, when no value is found.
In Prime the situation is a bit different because you also can provide your own comparison function. So we can do it that way:
So one point for Prime, but still millions of points against 😉
