Change field type to filter in question editor


I can't modify change field type to filter in question editor, i try this (cf screenshot 1) : change the field "SaisonAnnee" from "date" to "quantité".

But when i do that, in my question editor, i can't filter with the new field type, this i always a date filter type (screenshot 2)...

I try to delete cache too but i have the same problem

thanks in advance.

Metabase has that field saved on its internal database as a date. Try modifying the base type in Metabase field table

It's OK !
thank's a lot
