I have a Random gen but theres a problem

I have randomly generated swords

but there's a problem I pick up the sword or buy the swords.

it goes one generation ahead it seems I've been trying to fix it for weeks

for people curious the code is just setting a variable linked with an array to set animation of the weapon part and setting the stats based on which animations are playing

I'm not sure if I completely understand the problem, however it's might be worth noting that arrays are zero based, so if if you want the first item of an array you would request 0; if you want the 7th item of the array, you would request 6 and so on
