Blasphemy Error

When I equip Blasphemy with a curse, I get an error "Missing socketed skill" with an exclamation point in the upper right of the icon, and I can't activate it.

If I open the information panel for Blasphemy, it allows me to select weapon set 1, but weapon set 2 is showing red and is not selectable.

When I select weapon set 1, it appears to override the error and shows it as active, but it doesn't reserve spirit and isn't actually active.

I've tried with several curses, and I've tried removing all other reservation gems, but nothing works.

I have the same problem

Same here. Besides trying everything OP did I also tried using different level of Curse, didnt work.
