Jay,
You cannot redefine a Favorite (or a placed object) as you are doing with the US SE9 library. The parameters and behavior of the parts have changed and so parameter transfer from an earlier library to the newer one will not result in something usable in most cases involving windows and doors, which GS heavily reprogrammed.
What you are experiencing is what would have happened with the original SE 9 library (library parts same names as old 9 parts) if the SE 9 library had been loaded instead of the 9 library. Same thing as parameter transfer - and windows and doors would have been garbage.
You've discovered a subtlety of the 'new' (October) US SE9 library. The new version can load alongside the 9, 8.1 and other libraries just fine because of the renamed objects - and automatically matches earlier SE9 parts because of a common internal ID - but using parameter transfer will give bad results as you have seen. This is really no different than if you took a 6.5 window and tried to parameter transfer into a 9.0 window. Unpredictable.
I have heard from others offline of their frustration with this and can feel your pain.
😉 But, there is no simple way to redefine your Favorites in this case.
On the bright side, the word is the the SE9 library is the basis for the AC10 library, so we can only hope that time spent defining Favorites based on SE9 will be an investment that continues to pay off with AC10.
