my comments do not show and i stopped getting notifications for likes or replies on my comments

as u can see, my notifications are full of people liking or reposting the same repost as me. most of my comments are now unavailable. im not saying i don't repost, i repost a lot, but i do get at least one notification of someone liking my comment. i don't get that now. i cleared the cache, reinstalled tiktok, but im still facing the same problem. what to do?
