Configuration successful but never gets imported I have some changes in core.entity_form_display.node.news.default.  When I run drush cim -y it says it is successful but it actually never imports it.

drush cim -y                         
Collection  Config                                      Operation                
             core.entity_form_display.node.news.default  update
Import the listed configuration changes? (y/n): y
The configuration was imported successfully.            [success]


The changes are removing field groups from the form display.

If I try to import via UI it also says it is successful but it never gets imported.  I don't get any errors in my error log.



I tried to make some other configuration changes like changing the site name and it works. It seems to be an issue with Field Group or at least when deleting a field from from a form display.
Sounds like a known core bug: https://drupal.org/node/2666392
