Drupal 8 (v. 8.2.2)
DS 8.x-2.6
Boostrap (8.x-3.0) Subtheme

I need to set Expert Field Template for a Taxonomy's term field, but it doesn't save. It's strange because it shows Field template: expert in the "Manage Display" tab, but when clicked on , it shows as if the "Minimal" Field Template was chosen. I select Expert again, set it up and click "update". It doesn't update, it reverts back to default.

I don't know how to troubleshoot this.
