System.ArgumentException: No two choices should have the same ID

We have many webs (SPWebs) where content types have duplicate SPFields. Nearly
all these sick content types have got created when Infopath form is published as
content type to a Infopath library.

The duplicate SPFields are perfect duplicates,i.e.
GUIDS are also same. When I try adding\editing fields say in a list or web
content types ,An error is thrown. On cheching ULS. The error mentions about

"System.ArgumentException: No two choices should have the
same ID
                 at Microsoft.SharePoint"

Each time I need to update content types
or fields, I cant to it through UI.I have to use PoweShell.
