Filter dropdowns not working on dashboard

The other day my dashboard filters were working as they should. It was providing a list of all available options. Today, it is no longer doing so.

Here is a video demonstrating the issue.


Which version of Metabase? Which database are you querying?
Have you (or someone else) made any changes to the dashboard or questions on that dashboard?
There’s a known issue, where having filters connected to different questions, which uses different tables will not show the dropdown.
But if you didn’t change anything, then the only thing I can think of would be the sync/scan done every night failed for some reason, but you would have to look at the log.
