Can't bulk update view reference fields using VBO

This may have been flagged elsewhere, but it doesn't look like it and since the error below relates to this module rather than VBO I've added the issue here.

We have a load of migrated content on a site and added two new view reference fields to the content type that has been migrated. The field has a default view set but obviously this doesn't apply to existing content and we have a lot of nodes. I'd like to bulk update the view reference view to the default value, but on ticking the checkbox when trying to set parameters for the field value nothing happens and this error occurs:

Notice: Undefined index: bundle_enterprise in viewreference_select_process() (line 858 of ...sites/all/modules/contrib/viewreference/viewreference.module)
