Ah, I see you don't follow my (sometimes) daily musings. I chatted about the two communities from that instance appearing on this version on the Wednesday and Friday lists.
Anyway, I've eventually got around to messaging the mod of those communities, asking them to revert the community tags back to NSFW, which they have done so. Whether the lemmyverse crawler picks up on the change in time for next list is unknown, but even if not, they won't appear in the SFW lists after that.
Searching for 'support' on your instance gave me https://lemmy.ml/c/lemmy_support.
It says it's for 'Lemmy' rather than lemmy.ml specifically, but I guess it'll be read by the right people.
I didn't have the same issues you had. Maybe a browser issue.
