This is happening because they're both trying to modify the change_form.html. What you can do is add the html that one of them is trying to add in your own change_form.html either on model level or global level then let the other one extend the change_form.html on top of yours.

For example:

Create if you don't havetemplates/admin/change_form.html with the following content (copied from the FSMTransitionMixin)'s admin:

{% extends 'admin/change_form.html' %}
{% load fsm_admin %}

{% if save_on_top %}{% block submit_buttons_top %}{% fsm_submit_row %}{% endblock %}{% endif %}

{% block submit_buttons_bottom %}{% fsm_submit_row %}{% endblock %}

{% block after_field_sets %}
    {{ block.super }}
    {% fsm_transition_hints %}
{% endblock %}

and use this version

class PIAFormAdmin(GuardedModelAdmin, FSMTransitionMixin)

This works but it's being applied to every model even ones that dont have the mixin. Leading to a "object has no attribute 'get_transition_hints'" error as a result.
