Activating plugin causes 404 errors

Good Morning,

I am attempting to install the Directory on Real Estate theme and is having no luck. For some reason after installing the plugin, I can no longer access other custom post pages. Example, with property being the custom post type and "wood-run-place" being the post name. When I uninstall Directory, accessing other custom posts works just fine.

My Pretty Permalink is set to /%postname%/.
What gives? Please help, do I need to do a line of code in my functions or .htaccess file?

Thanks much,
