Your registrations are still looking for the style under Preset styles, you will have to manually re-add the files that aren't on the sx700 by loading up each registration memory, and re-saving with the correct pathway.
In the future, to avoid having to reprogram style pathways, copy all the styles you need into either a USB stick or the user area, and the put those same files in the same directory pathways on both keyboards
As for the sounds not showing up, Genos has S.Art2 and Revo voices which the sx700 won't even attempt to load. Either avoid both, or again, remap each registration memory.
Its kind of sad that Repertoire finder no longer exists, as it would find the closest style/ voice no matter the source/destination keyboards.
And yes, when I re-use a registration on a different keyboard, I generally use the "all styles on same usb stick" to avoid the style pathway remapping (although Murray Best's registration manager *does* let you change that pathway), then I just have to worry about mapping sounds and octave shifts (which aren't the same between CVP and portables)
