Taxonomy spaces drops prefix on homepage view - bug or misconfiguration?

I have set up a vocabulary to use with spaces and have defined several terms with prefixes. When I go to one of those prefixes it redirects to the url of the feature that is set as the homepage but drops the prefix. For example:
If a blog feature (with url of blog) is set as the home page for a given space (/students), when I go to that space I am redirected to /blog instead of either staying at /students or being redirected to /students/blog. This also happens when saving the settings on a taxonomy spaces page like /students/spaces/features - I end up on /spaces/features. Cache has been cleared multiple times. I originally had the global redirect module installed and I disabled and deleted that based on some issues in the purl queue. I'm using the latest spaces, context, and purl releases.

Looking through the code it seems like I should be seeing more settings than just the prefix on each taxonomy term edit page...but that's the only strange thing I've been able to find so far.
