Archers Armor Factor

2 of 3 archers got same armor factor while using 100% merchant armor but the 3th one somehow is missing 11AF.

Ranger AF unbuffed: 606, AF buffed with 75 value charge 681.
Every armor part 100% give Effective Armor: 121.

Scout AF unbuffed: 595, AF buffed with 75 value charge 670(Missing 11 AF).
Every armor part 100% give Effective Armor: 119.

Hunter AF unbuffed: 606, AF buffed with 75 value charge 681.
Every armor part 100% give Effective Armor: 121

1)Log every archer in each realm,
2)Buy merchant MP armor,
3)Check your AF and effective armor of item,
4)See that 11 AF is missing on scouts.
