I've been looking at it.   I've never seen anyone install Joomla in a subdirectory before.  Not that it is necessarily wrong but, OpenSEF seems to include /joomla/ in your URLs no matter what your .htaccess file says.  I'm no expert in SEF so you may want to inquire at the OpenSEF site.   You could try to go to "Manage Sites" in your OpenSEF config and add the /joomla folder to your Base URL.  If that doesn't fix it then I suggest you go to the OpenSEF site for support. 

Clearly the extension doesn't like the paths being different.  Between version 0.13A and 0.17A something changed that requires the path to be the same.  This is only a symptom of the real problem.  The real problem being that the URL path is inconsistent.  Fix that and the symptom will go away. 

Good luck with that.
