Need more info. Are you sure the install type is actually changing? Have you tested this with other youkai?

I've tested it on all youkai. Different element. It will use the prior element type, pretty much like the game reading the last youkai element instead of the new.

So fire into ice will still give you fire. If you use something else on top of that, any other youkai element, you'll finally get the ice but not the new element. It pretty much keeps doing that until the battle ends.
