Admin templates are not rendering properly

Upon creating my own panel in OpenStack Horizon I am unable to properly view the admin panels (Overview panel: Pie Charts not appearing, Instances: Unable to generate Instance but can view possible instances to choose from). This occurs when my new panel is 'enabled' within the enabled folder. The panel that Ive added is not Horizon-centric, and the 'magic' of Horizon is not taken advantage of (I find its syntax odd). Any idea as to why the admin panels are no longer rendered properly? It seems to be a template issue but I have no idea how to fix it.

settings.py code:

# Standard Library
import logging
import os
import sys
import warnings
from collections import OrderedDict

# Django Library
import django
from django.utils.translation import ugettext_lazy as _

# OpenStack Library
from openstack_dashboard import exceptions
from openstack_dashboard.static_settings import find_static_files
from openstack_dashboard.static_settings import get_staticfiles_dirs

I had stored static variables in settings.py to access in a custom dashboard. As a result the Horizon dashboards were broken. The static variables should be store elsewhere.
