I don't understand your question.  It is not unusual for the group median to equal a value in the data.  Where it gets somewhat messier is in that the definition of "median" can vary and that can impact the estimations.  Note that even though these p-values are called "exact" they are not the brute-force computations that we learned in graduate school (those approaches rapidly become prohibitive when the sample size exceeds 10).

Perhaps you could read the documentation referenced in

and reframe it.
