SBML generation problem for WP5113

I am not sure I understand the question, so a problem to further explore. xpath reports:

$ xpath -e "/sbml/model/notes/body/p/text()" sbml/WP5113.sbml 

not well-formed (invalid token) at line 1, column 0, byte 0:
{"reason":"lcsb.mapviewer.model.map.InconsistentModelException: [StateTransitionReaction iddc9a88f6]\tProblem with exporting bioEntity","error":"Internal server error."}
^
 at /usr/lib/x86_64-linux-gnu/perl5/5.32/XML/Parser.pm line 187.

With the SBML webserver reply which should have been SBML but it instead:

{"reason":"lcsb.mapviewer.model.map.InconsistentModelException: [StateTransitionReaction iddc9a88f6]\tProblem with exporting bioEntity","error":"Internal server error."}
