I have several content types based on Folder with a couple of fields.
Some of them are experiencing some strange behavior.
The fields are there, and the data is being saved, because I can see them on the list and I can add them to the view fields, but I cannot see them in the display, edit or new forms.
I have compared the schema from a working CT and a non working CT and the difference is the part below.
The properties ShowInDisplayForm and so on are set to True on all areas.

<XmlDocument NamespaceURI="http://schemas.microsoft.com/sharepoint/v3/contenttype/forms">
<FormTemplates xmlns="http://schemas.microsoft.com/sharepoint/v3/contenttype/forms">
<Display>ListForm</Display>
<Edit>ListForm</Edit>
<New>ListForm</New>
</FormTemplates>
</XmlDocument>

In my schema I just have the content type id, name and field refs. Not sure if I need anything else like the above, and I wonder why it works for some content types just not others (perhaps the others were manually added).
UPDATE:
Creating a new form for the library/content type shows the missing fields.
I would like to fix the underlying issue, rather than creating new forms, also because Upload.aspx is experiencing the same behavior and since I am in a position where I can delete the libraries and content types and redeploy the solution.
