One Developer Can't Set Breakpoint in Django Templates

Hello -

 I have three developers, all on Mac OS 10.14.4 Mojave, and Python 3.6.8 via PyEnv.  They all have PyCharm 2019.1.2 installed via Toolbox.

 Two of them can do these steps:

1.  File->New Project->Django
2.  Choose New VirtualEnv (based on ~/.pyenv/versions/3.6.8/bin/python)
3.  File->New HTML file in the 'templates' dir.
4.  Add {{ url 'test' }} to body of that file
5.  Click next to that new line to set a breakpoint
6.  Run Django with Debug

One of my developers can't set the breakpoint for the new line. I've tried it on their machine, and it won't enable setting the breakpoint.

I've tried removing the ~/Library/Preferences/PyCharm20* and ~/Library/Caches/PyCharm20* directories, and deleting and re-installing Python and PyCharm, multiple reboots, etc.

They are able to set breakpoints in .py files just fine, but not Django templates.

Confirmed Python Template Language is set to Django in the newly created project, virtualenv is set, template folder is pink, etc.

Really confused as to why debugging won't work in a brand new project for just this one person! So odd!
