"Summary" field not maintaining data · Issue #30 · dshanske/indieweb-post-kinds https:/
The field "Summary" under the "Citation" tab in prior versions was constantly self-updating with details of the original website/URL and not allowing the editor to make permanent changes which then propagate to their site.
Under the changes in v2.2.0 it seems like one can finally make changes to this field manually, but after saving/publishing, the field seems to self-delete and any future updates to the post result in the "Summary" text disappearing from the final post (at least from my tests with bookmark post types.)
