craft mechanubis weapons

[Kinggg]

Have a nice day. I have a bound mecha staff and I wanted to craft it into a mecha dagger. I bought recipe weapon reshaping worth 7.5k tokens from zodias vendor and also bought the mecha alter stone. But nothing about transformation was opened in the craft section. I checked the recipe and it cannot be opened from the inventory either. Where is the mistake? Let me know information please if possible, tysm.
Best wishes.
