As indicated in the readme file and the code, puzzle and solution bodies should be either of the form -body-html or -body-md. Most of the sample solutions (used by loaddata) do not follow that syntax:
{% block solution-body %}
and therefore fail to load in the front end. Only solution_bodies/sample.html is correct.
All the other ones should use
{% block solution-body-md %}
except solution_bodies/diagramless.html which should use
{% block solution-body-html %}
