SharePoint 2010 Import error - The name 'FieldLookupValue' is not permitted


I have been importing Lists from our SharePoint site using the TDA (version 3.1) Import wizard successfully.

However just tried importing a new list which has a column containing sample data = Microsoft.SharePoint.Client.FieldLookupValue

When I try to import I receive the following error message:
The name ‘FieldLookupValue’ is not permitted in this context. Only constants, expressions, or variables allowed here. Column names are not permitted.
Has anyone come across this issue and can advise how to fix?

Thank you in advance.
