Resolved

I set empty cells to hidden, but that caused the configure icons to move around.

I used fences on a site and copied the field template.

It needs to be enabled for the template to work correctly.

Is there a way to toggle usage of the template if it's enabled?

Remove border and Advanced title so it looks like the other columns.

Table may not be showing groupings correctly.

Context

Something is wrong with the layout.

Using this module: https://www.drupal.org/project/media_library_theme_reset

Field group tab borders have a gap.
