Custom Field Cross-Space Integration Issue

I seem to be having an issue where a custom field that was created in our company's main space is transferring over to other individual spaces where they aren't needed. I've gone through the settings multiple times and currently that field is not set to the individual's space that it is appearing in. Inside the individual's space the custom fields tab appears like the image below. Both the Landscape Comments and Paul's Comments have been removed from this space in settings. Yet they still appear here? Am I missing a step somewhere? There are other custom field created in the same way as these that are not appearing. I know this cross space fields feature is rather new so possibly a bug? Any help would be appreciated :)
