Items created or edited with op have no list subtitle

Items written by the 1Password CLI (op 2.41.1) show no subtitle in the app's item list (1Password 8.x for Mac). Items saved in the app show their type there; for an API Credential, for example "bearer." Items I created or edited with op show nothing under the title, even when their type field is "bearer."

In the CLI's JSON, the items that show a subtitle have "additional_information": "bearer". Items written by op have "additional_information": null. That's true after op item create, after an assignment edit (op item edit <id> username=…), and after op item edit <id> --template <file>.

Opening the item in the app, choosing Edit, and saving without a change doesn’t fix the problem.

Instead, change the title in the app (add a space), save, then remove the space and save again. After that the subtitle shows and additional_information is set.

To reproduce:

1. op item create --category "API Credential" --title "subtitle test" type=bearer
2. op item get "subtitle test" --format json | jq .additional_information prints null, and the app's list shows no subtitle for the item.
3. In the app, open the item, Edit, Save without a change. Still no subtitle.
4. Edit the title (add a space), Save, remove the space, Save. The list shows "bearer."

Expected: op sets the subtitle when it writes an item, or the app recomputes it on any save.
