The post_type value is blank in query_vars for geodirectory-archive.php

I have 3 post types created in GeoDirectory:

1. gd_place
2. gd_event
3. gd_people

I’m customizing geodirectory-archive.php for category pages and I’m having trouble getting the “post_type” value from query_vars for gd_people category pages. It works for gd_place and gd_event category pages, but not gd_people. Here’s example:

1. People (gd_people) > Coaches – https://tennisletics.com/explore/people/category/coaches/
2. Place (gd_place) > Resorts – https://tennisletics.com/explore/places/category/resorts/

Notice when you inspect code, the body classes are slightly different indicating the use of different template:

1. People category – “tax-gd_peoplecategory term-coaches term-166”
2. Place category – “post-type-archive post-type-archive-gd_place”

In summary, it looks like Place and Event categories are displaying as post type archives, but People categories are displaying as taxonomy archives.

Anyway I can make People category pages display like Places and Event category pages; post type archive rather than taxonomy archive?
