Settings not saving

Problem/Motivation

I Want to change the default setting for a given breakpoint. Unfortunately no changes on the /admin/config/content/ckeditor_bs_grid page take effect.

Steps to reproduce

Open the page, select any breakpoint and column layout and make a change to any option. Eg. Set default layout to "By Sort Order", move one of the options to another spot. Change the weight of any of the options. and Save the changes. Look at the same breakpoint and column layout and all changes have reverted to default.

Proposed resolution

The changes should stay.
