I'm a little confused about this fender tag - although I've decoded all the codes, it seems to have an extra code (or duplicated code) where it shouldn't on the second line from the bottom:

M33 R11 V1X END
A04 C55 G33 H51 J25 M21
R6 R6 P6X X9 A11 137816
E31 D31 LP23 D9E XXXXXX

The R6 code for red - unless my mind was playing tricks on me and I'm imagining things - was repeated. Is this possible?
