Further math A* (Edexcel) - confused, any help?

Hey everyone,

I got my Math and Further Math A level results today, and ended up getting A* and A respectively. Although, my UMS for my modules allow me to get A* in both. Below are my A level math module and FM a level math module assignments:

A Level Math:

C1 - 83
C2 - 83
C3 - 89
C4 - 94
S1 - 98
S2 - 92
Total (539/600 meets 90% average for C3 and C4)

A level Further math:

FP1 - 73
FP2 - 95
M1 - 96
M2 - 82
M3 - 88
D1 - 78
Total (512 - doesn’t meet 90% A2 module average)

Now below, is what my ideal combination of modules would be, getting me A* in both, maths AND further maths:

(Normal maths)
C1 - 83
C2 - 83
C3 - 89
C4 - 94
M1 - 96
M2 - 82
Total (527/600, 90% average in C3 and C4 met, and A* in math)

(Further maths)
FP1 - 73
FP2 - 95
S1 - 98
S2 - 92
M3 - 88
D1 - 78
Total (524/600 - 90% average between FP2, S2 and M3, 91.6% - meaning, I get a further maths A* as well)

So why do you all think Edexcel just gave me a Math A* and no furher Math A*? How do I get this fixed? Am I overlooking something?
