All of my repost disappeared ?

I'm confused I was going through my own repost to remove them all starting from today up to the oldest one. When I got at like june 2025 I recharge the page to chevk my progress and All the one older than today (so older than the one I was removing) disappeared on their own?

I dont mind it I wanted everything gone anyway but I'm very confused as to how this happened ? I dont think anyone else is connected on my tiktok account lol
