Cannot add grouped by &filtered by in custom question

When I ask a question in custom with my own dataset, I can't find how to add "filtered by" and "grouped by", but when I use sample dataset like Order or Product I can find the button to add " filtered by" and "grouped by",I don't know what's wrong with my Metabase,!can anyone help,thx!

Version, browser etc?

Happens to me sometimes. I usually refresh the browser (maybe it takes a hard refresh) and it is solved. If not, try to rescan the database as well - it has happened to me that Metabase wouldn’t show the tables even in the table selector, and a quick database rescan did the job.
