So, i posted that thread mistaking a conflict between a fins patch and GSaSR, instead it's between GSaSR and Better Shaped Weapons. To put it simply, BSW simply remove any sheath from 2H greatsword. And no, i didn't selected the "no sheath" option while installing it. I simply don't understand how to resolve that conflict as even if i put GSaSR after BSW, they simply don't appears. Edit: It's somehow resolved. For some unexplained reasons, BSW seems to only remove the sheath of the greatsword i had equiped prior to installing it. I bought an iron, steel, and a iron enchanted (since i had an iron enchanted greatsword for testing) and they all add the sheath. I don't get what's happening but i don't care anymore, i spend too much time on that.
