Filter dropdown not updating / Syncing with database

I have a table (Postgres DB) with just 5 rows, and I'm using a dashboard filter (field filter on category). When I insert a new category value into the database, it:

  • Appears in the table or chart data
  • Does not show up in the filter dropdown

Even after running "Re-scan field values" from Admin → Databases, the filter dropdown still doesn't update.

Manually going to:

Admin → Data Model → [My Table] → [category field] → Discard saved field values
…was the only action that forced Metabase to refresh the dropdown list correctly.

Whats the solution here?

What version of metabase are you running?

v1.53.8
