OC5 editor v2 Structure of Option files has changed?

[Timo-Breumelhof]

I'm upgrading a client to Open Content 5 and apart from the things mentioned on here: https://opencontent.readme.io/v5.0/docs/migrating-existing-templates-to-builder-v2 I noticed something else. For most nested templates the value in the options file are ignored (for templates created in OC 4)

Here's the options file:

{
    "fields": {
        "ModuleTitle": {
            "type":"text"
        },
        "Items": {
            "fields": {
                "item": {
                    "fields": {
                        "Title": {
                            "type":"text"
                        },
                        "Text" : {
                            "type":"ckeditor",
                                "ckeditor":{
                               "toolbar": [
                                { "name": "text", 
                                    "items": ["Bold" , "Italic", "Underline" , "RemoveFormat"]
                                },
                                { "name": "style", 
                                    "items": ["Format"]
                                },
                                { "name": "layout", 
                                    "items": ["Table" ,  "NumberedList", "BulletedList", "Outdent", "Indent"]
                                },              
                                { "name": "link", 
                                    "items": ["Link" , "Unlink"]
                                },
                                { "name": "Img", 
                                    "items": ["EasyImageUpload"]
                                },
                                { "name": "Source", 
                                    "items": ["ShowBlocks", "Maximize", "Source"]
                                }
                                ]
                            }
                        }
                    }
                }
            }
        }
    }
}

This works in OC4 but not in OC 5. I think this is an OC 3 type options file structure right?

If I change this:

"Items": {
            "fields": {
                "item": {
                    "fields": {

to:

"Items": {
                "items": {
                    "fields": {

(and remove a } at the bottom

The options file does work correctly
