When working with GUI plugins that are registering custom global settings by creating a plugin for the default setting below local/share/check_mk/web/plugins/config and a global setting declaration for WATO below local/share/check_mk/web/plugins/wato, the edit dialog of the global setting did not work in all cases as expected.

Some times a KeyError: '<setting-name>' exception was shown in the GUI.
