relationships will map to the initial query but not correctly when two fields in one table map to one field in another. You need to have an instance of the lookup table for each of the two fields - this sql should work for you
Code:
SELECT tbl_Dt_Pers.ID, tbl_Dt_Pers.Nm1, tbl_Dt_Pers.Perlty, tblu_Dt_UserDesc.ID, tblu_Dt_UserDesc.GrpLvl, tblu_Dt_UserDesc_1.DescL
FROM (tblu_Dt_UserDesc RIGHT JOIN (tbl_Dt_Pers INNER JOIN tbl_Dt_PersBldg ON tbl_Dt_Pers.ID = tbl_Dt_PersBldg.PersID) ON tblu_Dt_UserDesc.ID = tbl_Dt_Pers.Perlty) LEFT JOIN tblu_Dt_UserDesc AS tblu_Dt_UserDesc_1 ON tbl_Dt_Pers.Perlty = tblu_Dt_UserDesc_1.ID;
