Chrome (desktop/mobile): Deleting posts and comments doesn't "stick"

I successfully select the delete option when I attempt to click it for posts and comments. I see the confirmation popup and confirm, and my comment or post appears to be deleted. However when I refresh the page, the comment is still there. People are also able to still interact with them, and I can pull up my profile on a different browser on a completely different device and the deleted comment/post is still there. Selected Desktop web but I'm pretty confident this is not a client-side issue. Edit: I just checked on yet another device in a browser I'm not logged into, and a post I definitely deleted still shows up in the subreddit it was in, so something is definitely going wrong with deleting things.
