I am patching a SharePoint List from a collection and am getting the following error.
Thumbnail: The specified column is read-only and can't be modified (see photo). The information IS patching the SharePoint list. But the error is going to be confusing to users. Any idea why this is occurring?

@NigelP Thank you for your quick reply. When you say list settings - are you referring to the SharePoint List? If so, see below.
1) I see no ""Thumbnail" site column in your list.
2) Also when you view the list, check the fields to the right hand side of the view and see if a field called "ThumbNail" has crept in. It might be a hidden field.
3) Does your Patch Statement reference a "Thumbnail" field ? If so remove the reference to the "Thumbnail" field.
If all of the above fails - Try recreating the list with another name and see if you have the same problem.
It might be that you have a corrupt list.
