Threads of Fate

I'm playing this wonderful game and in my monster menu it says I have an old transformation. I've done everything I can think of to get rid of it but nothing seems to work. Could somebdoy please tell me how to trash the old ones?

All of you who've looked have no idea?! As usual, everybody elses simple questions get answered but mine never do.

Just get a new one, eventually they start throwing out the oldest ones

BTW this game is brilliant stick with it
