In Django 3.x, in admin interface, when list_filter is enabled, it appears over the change list (data table). There is no table resize to make space for the list_filter, so it hide some data.
Ken thanks a lot for your response. You are right, I forgot that I use a custom changelist.css since version 1.17 I think. Making the custom changes to the css but for 3.2 did the trick. One lesson more learned.
