Array Problem

a question.

look at left arrow that I marked, I set weapon unit to 10


in the field of weaponid3_unit is 10, it's correct. but why in other field is filled with random number?


I purchased a DE in line 3 and it successfully inserted with the right field weaponid3_unit


and the question is why in other field besides weaponid3_unit is filled with random number? the value of weaponid3_unit is correct
