We had the same issue. I think it’s caused by an incomplete implementation of Discourse [dropping the category column](https://meta.discourse.org/t/101352) in recent versions. When it happened to me I blamed it on us using a non-release version of Discourse from Github, which obviously may contain incomplete feature implementations. Which Discourse version do you use?

For now, I have fixed it by re-adding the category column in the table content by installing the “Add Category Column” theme component:

The problem is that an add-in is generated. I’m trying to figure out what extension he’s doing.

Odds are this is happening cause you have a theme component or theme that is overriding the whole template, does the issue also happen in [safe mode](https://meta.discourse.org/t/53504?silent=true)?

Indeed! The column header mismatch problem is not present in [Safe Mode](https://meta.discourse.org/t/53504?silent=true).

So I know where to look. Thank you!
