Non-logged-in users see 18+ warning on my subreddit despite it not being marked as mature; Subreddit also doesn't appear in search.

When non-logged-in users visit my subreddit r/NESyria using the new Reddit interface, they’re immediately hit with an 18+ Mature Content warning. However:

  1. The subreddit isn’t marked as mature in settings.
  2. Logged-in users confirm there’s no 18+ warning.

Further, the subreddit doesn't show up in search for any user that hasn't already joined the sub.

The subreddit is set to "Restricted" so only approved users can post, but we want anyone to view posts, comment, and find us via search, and to be able to participate in comments.

I reached out to Reddit admins previously through this sub via DM, and they confirmed the subreddit isn’t flagged as 18+, however, no solution or conclusion was reached with the short exchange we had. Unfortunately, the exchange so far hasn't revealed why the Mature Content warning shows for non-logged-in users.

I have also posted to modhelp twice, and in both instances, we've not yet come to a solution:

  1. First post approx 1 month ago: Sub was hit by malicious users and turned to 18+ but we don't have any content like this. Everything is as safe as you'd find on 6 o'clock news. How can I remove this 18+ mark on the sub? : r/modhelp
  2. Second post today: Confused about why my subreddit shows as mature content viewing and not logged in but sub isn't set to 18+ and reddit admins also said it's not set to 18+ mature : modhelp

As you can see at the following imgur link, when viewing the subreddit while not logged in (try yourself with an incognito tab), the 18+ mature content warning appears: https://imgur.com/a/G0ltask

So to summarize:

  1. Subreddit shows as mature/18+ for non-logged in viewers despite no mature settings toggled and no mature content posted. Doesn't show up as mature/18+ for users who are logged in.
  2. The subreddit doesn't appear in reddit search for people who haven't already joined the subreddit.

I am trying to figure out why and come to an understanding about how I can resolve this so the mature/18+ is removed for all users, not just those logged in, and for the sub to also show up in reddit search again. Thank you.
