Is my reddit acting up?

Image 1: a post I saw about moving subs, so I responded. Image 2: my response showing under my profile Image 3: the comment shows for me Image 4: but it doesn't show for my alt when I go onto it.

The thing is.. this SAME issue has happened ONLY on this sub for me and when I made comments on the situation. It shows for me but not for my alt or when I use anonymous browsing. Is this a bug..? What's going on? If anyone has a reason I would be glad to accept it.. I am just very confused rn.. ty for reading 😭🙏💕
