If you did your first version with 360° by accident his might be releated to a problem I reported ages ago: The deovr client caches the projection properties in an internal database and changing these properties on the server doesn't do anything.
To work around this you have to change the title as well, that way the local database does get a new entry with the updated projection properties.
The internal database makes sense if there is no additional metadata provided. However, if json from the server is updated that internal database really should be updated, at least for the properties where deovr doesn't allow the user to override them.
