PPG Wavegenerator bank import not working?

[aMUSEd]

I am trying to transfer several banks I have in the desktop version over to the iOS one. I know it should work as I had it loaded on my old iPad using the old system of importing files via iTunes, but I now have a new iPad Pro and am on Big Sur and the process seems to have changed. Now you access the iPad files via Finder, I can see a location that looks like Wavegenerator's file location and have dragged several banks into it but they still don't show in the bank manager. Not sure what else to try?

Any one else come across this?
