sync error with Workspace "Data in this list references content type "", which is no longer in the list schema"

Dear,

I saved a document library containing folders and files as a template to use it as a template when I created a document library.  It contains a lot of folders and files.

When I tried the document library to sync with workspace it gives an error "Data in this list references content type "", which is no longer in the list schema"

I checked with this error and I found out that it has issue with onenote file, but my library does not contain any onenote file. 

I wonder if there is any issue regarding the number of folders to sync at a time because when I tried to sync with document library similar to the big library but lesser folders and files. 

Thanks
