Optional OpenStreetMap messages show for translation

I see two messages for translation at https://translatewiki.net/w/i.php?title=Special:Translate&group=out-osm-site&language=he&filter=%21translated&action=translate :

Osm:Accounts.edit.public_editing.enabled_link
Osm:Accounts.edit.contributor_terms.link

They are marked as optional in the configuration, in groups/OpenStreetMap/OpenStreetMap.yaml:

TAGS:
  optional:
    - html.dir
    - accounts.edit.openid.link
    - accounts.edit.public_editing.enabled_link
    - accounts.edit.contributor_terms.link

I added these keys a few weeks ago, and I even think that at some point they were correctly configured as optional. But now they appear as not optional. What's wrong? Did I make a mistake in the configuration? Is there a glitch in configuration functionality?

Thanks :)

I've tried to address it here: https://gerrit.wikimedia.org/r/c/translatewiki/+/881921

However, it's a bit odd that some messages with '_' and some need '+'.
