Blessing Of Pet Tamer trouble.

I was speaking earlier today with Ente about an issue with blessings of the pet tamer but he never got round to explaining it properly.
I'm sure I wasn't having this issue before the candy cane update.
Basically I have an Augu/Mammoth pet which is D(1)/C(2)/B(2)/A(3) I want to take it back using blessing of pet tamer to level C so I can max it out now I have the money. Now normally each blessing you use takes you back to 99% on previous level but all it seems to be doing is changing the current level without reverting.
