Lancaster bomb loads

During research on my fathers (KG THOMPSON DFC ) tour with 101 squadron (Lancasters) December 43 to may 44. I was looking through the ORBs and came across what appear to be bomb loads of 16 bombs. The raids on Aulnoye, 10/4/44 & Rouen 18/4/44 both show, for all aircraft listed, loads of 8x1000lb MC, 4x1000lbGP & 4x500lb MC. Also for the Hasselt op. on 15/5/44 the load was for 15 bombs 8x1000lb MC, 3×1000 USA , 4x 500lb MC. It was always my understanding that the standard configuration was for a max of 14 bombs (per AP 2062A). Google did not enlighten me (nothing new there then)

Anyone have any ideas, unfortunately Dad is no longer around to ask.
