Django Template Breakpoints Ignored (some of them)

I'm debugging a Django template in which I have multiple breakpoints.

Only the breakpoint on the first {%extends%} line is recognized, the rest, no matter what line they are on, are ignored.

Ideas??


{% extends "django_ace.html" %}  <–Break works here.  Nowhere else.
{% load humanize %}
{% load staticfiles %}


{% block title %}
Classroom IQ - Gradebook
{% endblock %}


{% block css %}
<link href="STATIC_URLtable.css" rel="stylesheet" />
<link href="STATIC_URLgradebook.css" rel="stylesheet" />
{% endblock %}
