Description field not coming through for one collection only

[cstilstra]

Hello, I have multiple collections that use the same fieldsets for things like content (including the field that SEO Pro pulls the description from) as well as images. When I view entries on the front end from collection A (Press Releases) I get the meta tags I would expect (description, og:image, etc.). When I view entries on the front end from collection B (Stories) I get all of the meta tags I would expect EXCEPT the description tags (description and og:description). Section defaults are set up the same for collections A and B.

Furthermore, if I modify the section defaults for collection B I am still unable to get the meta description fields populated. I can instruct collection B to fallback to the default site description and still no descriptions show up on the front end. Similarly, I can instruct collection B to use a hard-coded string as a description and still no descriptions show up on the front end. For whatever reason, it seems as though collection B just does not want to display meta description tags regardless of how it's set up, despite collection A having no troubles and virtually the same configuration.

I'm happy to provide any additional information that might be useful here.
