Tags not showing up in Admin Post List

I have been using tags since the beginning of this website. The last couple of post do not display the tags that I have entered in the post list on the admin page.
I have tried to disable all plugins but this does not help. I have tried a lot of the solutions posted everywhere on the forums and the internet. I used the default 2020 theme, this does not work.

Any help is greatly appreciated.
