Units are wrong on tutorial example 2

[mhemery]

I am talking of the second example of this page : https://sbml.org/software/libsbml/libsbml-docs/tutorials/
Clearly, given the rule : d(p4)/dt = p3/time parameters p3 and p4 have the same unit which is not the case in the samples provided just below (p3 is in metre_sq and p4 in metre_sq_per_sec).
