Yes, this is normal. X/Y information is stored differently now and will be lost on presets created with previous firmware.
I haven't updated yet so let let me get this straight...all the blocks my 8.01a presets after upgrading to 9.0 will be defaulted to the X state regardless how they are saved in 8.01a? And the easy fix is to just copy Y->X where ever necessary and all will be right again?
