For some reason I thought this wasn't an issue in the revised version of 777. Shows how deeply I've studied the correspondences!
In the "Notes" of 777 this is written - might be helpful to others:
"lines 15 and 28 should be exchanged on all columns based on the Zodiac or Tarot (i.e., VI-VIII, XI, XIV-XX, XXII-XLVII, XLIX, CXXXVII-CLXXIV, CLXXVII-CLXXXIII and CLXXXVI), not all columns throughout as the editors of 777 Revised state – T.S."
