The parcel ID for the existing parcel should be included in the LandXML in order for the parcel to be linked to the existing parcel in Landonline.
If the parcel ID is included, the corresponding existing parcel row will show populated parcel intent, parcel area and layer fields.
If the parcel ID has not been included, or is incorrect, those fields will remain empty. The simplest fix for this is to delete the parcel and use Add an existing parcel using the Existing Parcels panel or Add an existing parcel using Spatial view.
