We only want to display the [wpv-post-taxonomy type="ptfe-ol-seals" format="name"] field once as a dynamic sub-title for each taxonomy block of records.

So for each CPT post on this page, the Taxonomy name is appearing multiple times - each post.
We want it to display once, so it acts as a sub-title for each set of records.
This would be possible if it wasn't a search view, as this requires nesting of a post view inside a taxonomy view.
Where the taxonomy view will list the terms and below the terms the post view will list the results for that particular taxonomy.
However you're already using the taxonomy query filter for the taxonomy search filter so it wouldn't be possible. This is because the Taxonomy filter will be required for the post view to be filtered by the Parent Taxonomy view.
