Comments Not Visable

Hi everyone!! Ive just recently started making stuff again and ive realised that people comment on my videos but I cant see the comment nor does it give me a notification (sometimes it does but when I press on it, it's still not visible)...

I know this is what's happening because I have an alt thats used specifically to reply to comments i cant see because I feel bad for not replying and things.

The photos ive shown are from the same video but ones from the perspective of my main account and the other (with the visible comments) Is on my alt account.

Does anyone know how to fix this? I dont have filtered comments on or anything like that so I dont really know why it's doing that...

If anyone's got any suggestions it'd be greatly appreciated, thank you! :)
