the only solution i found was to add these rows manually from the DB

INSERT INTO UmbracoCampusME.[dbo].[cmsPropertyData](contentNodeId,versionId,propertytypeid,dataInt,dataDate,dataNvarchar,dataNtext,dataDecimal)
SELECT 
CmsC.nodeid [contentNodeId],
CV.versionid [versionId],
CmsPT.id [propertytypeid],
NULL [dataInt],
NULL [dataDate],
'' [dataNvarchar],
NULL [dataNtext],
NULL dataDecimal
FROM UmbracoCampusME.[dbo].[cmsMember] CmsM 
    INNER JOIN UmbracoCampusME.[dbo].[cmsPropertyType] CmsPT ON CmsPT.Name like '%FIELD_NAME%'
    INNER JOIN UmbracoCampusME.[dbo].[cmsContent] CmsC ON CmsC.[nodeId] = CmsM.[nodeId] AND CmsC.[contentType] = CmsPT.[contentTypeId]
    INNER JOIN dbo.cmsContentVersion  CV on CmsC.nodeid = CV.ContentId
    LEFT JOIN UmbracoCampusME.[dbo].[cmsPropertyData] CmsPD ON CmsPD.[contentNodeId]= CmsM.[nodeId] AND CmsPD.[propertytypeid]=CmsPT.[ID]
