But exist in the db, I cannot see or set a value for any of these dates in the setting page. This occured after upgrading to cms 12. Its on the startpage (home) and there are a few errors on the console log that may or may not be related:

widgets.js:2 The store was queried with a [string] but the entity id is a [undefined]       |         widgets.js:2

 Failed to load resource: the server responded with a status of 404 ()        |        editor.css:1


Has anyone ran into a similar issue and been able to resolve this? 

(Coincidentally, when creating a new start page the issue is not present.)
