Less comments than tiktok says there are

Recently, I have run into an issue cometime where when someone responds to a comment I made, I can't see it. Tiktok will for example say there are 3 responses to my comment, but then when I open the thread, it only shows 2. It's really annoying, I do not want to ignore people. Like in the images it says there are 4 comments, 1 main commment of mine and 3 responses. but when i extend the thread. its only 2. Anyone have any idea what causes this/fixes it? It does not matter if I am on mobile or PC.
