As I'm sure most of you did, before trading my KN5000 I transferred some of my favourite 5000 factory styles to the composer and saved them to disk just in case they weren't present on the 6000.
Now I'm getting an interesting error message when I load some of those styles into the 6000's composer and then try to transfer them to custom. The message is:

This data includes sound and/or effect memories in the custom styles. If you want to edit your custom style data, please copy it to the current panel using the custom style copy function set to "from custom style to memory bank" and after editing copy the data back to the custom memory.

The message doesn't make sense to me because it is telling you to transfer the data to where it is already located!

Any ideas?
