There is bug with pre-selected date filter (default filter widget value).
Problem is that when you are removing this pre-defined filter from top of query. It still applies it on background, for example you can click ‘X’ and will see that results did not change at all.
Will appreciate if you will fix it Metabase team
BTW we updated Metabase to the latest 0.33.3.
Let me know if you have questions regarding bug.
P.S I did not find this bug report across other bugs, thus created new one. Let me know if there is duplication report.
