Ancient Items not showing "Increase Stamina +5/10" option

[H2oR]

Hello,

I've noticed that ancient set parts in my MU server(ssemu season 4 v2.5.2) do not show the option "Increase Stamina +5/10".

I tried several methods:

- Killing Kundun and looting the drops

- Using a drop command as follow:
/drop 7 1 13 255 1 7 63 5
/drop 7 1 13 255 1 7 63 10
/drop 7 1 13 255 1 7 0 5
/drop 7 1 13 255 1 7 0 10



-Creating the items through the Maker

But none of the items are generated with this option:


Since I'm still new to this (and still learning), I would really appreciate some guidance on how to locate and fix this issue.

Thank you in advance!
