Pads won't save every time I reload cubase song

If the instrument is halion5 it saves, but in halion sonic2 it doesn’t save. the 8 pads that I use to control the sound. Any idea why? and if I try to save the program from halion sonic2 (hopefully with those pad settings) to be used in halion5 which can save, then I cannot find that saved program in halion5.
